Everyone gets a cheap computer for emails and since only one person will be doing 3D modeling at a time they can use the specialized Mac Pro.

Or is there some way to set up a KVM switch so that everyone has their own cheap computer but they can also cycle the Mac Pro screen to their workstation when they need to use it?

I don't suppose they could use a remote desktop connection from their own computer to the Pro (not for 3D modelling, anyway).
 
I hate to be the killjoy here, but wouldn't this setup be more expensive, more complicated, and slower than just buying a Mac Mini as a second machine?

The VM won't even have graphics acceleration available to it. And I think everyone has missed the original point of only having to buy software once. Legally (and activation wise), the VM isn't going to fix that.
 
Sure, you can have hundreds of user sharing a mac. You just need to set up the Getty process on OS X and buy a large number of Wyse VT-100 terminals.
 
Man, this is amazing. i never thought it would be possible. It actually work seamless?

This can very well revamp my small 3 ppl company, i can have 1 employer doing 3d modelling while another do Pages work and i respond to some e-mails.....in my Hex Mac Pro and avoid the hole let me use your computer thing

It would take a bit of fiddling to setup but yes, it would work, You'd only really want to do the 3d modelling on the setup that has direct access though due to 3D acceleration.

Is your spare keyboard the same as your main keyboard?

No, my main keyboard is one of the current gen Aluminium keyboards with numpad while the second keyboard is an old Apple Pro keyboard - the ones with the black keys.

No, it wouldn't be more expensive unless you went the Snow Leopard Server route. If you're prepared to do a bit of hacking to get Snow Leopard standard working in VMWare Fusion then all you'd need (apart from screens) is a licences for SL for each setup and VMWare Fusion - an OSX family pack would likely do. If you go the whole hog with the VNC/VMWare route then you'd just need a license for VMWare Fusion. Of course it's complicated but basically the more effort you're prepared to put in to the setup, the more money you could save.

Edit: With the VNC method (just giving it a try now) you might run into screen setup issues when changing screen resolutions etc but if you use identical sized monitors in your setup and make sure that each user's screens are set up like the layout I linked earlier then this shouldn't be too much of a problem.

Edit 2: Actually, I just tried it again and it did work with changing the resolution for the second user. I was just limited to the resolutions capable by my main display (so couldn't set it up to 1200x1600 portrait to fit nicely into my second display). It all seemed to work just as expected.

One computer running one copy of Snow Leopard with two clients:

vnc_linux_fastuser_snowleopard_vmware.jpg

Second display is running Linux Scientific 5.5 and is using vncviewer to connect to Vine Server running with port 5901 on a user activated via Fast User Switching running at a different resolution to the primary setup (accessing only one display - second display is moved to awkward location as I suggested earlier in this thread). VMWare is passing full control of my mouse and secondary keyboard to Scientific Linux which in turn is passing it straight to the second user.

The only reason the second user view isn't full screen is because the portrait resolution of my second display isn't listed in the options - this could probably be fixed if necessary via SwitchResX though. The only real problem that I can see is that VMWare's little top menu bar remains on screen at all times when the VMware isn't active by the primary user (which will always be the case in such a setup).
 
I see. I wonder if using the same model keyboard would make a difference?

It shouldn't. You'd get two identically named keyboards in the VMWare USB section to choose to connect to the machine and you'll have to guess but it will work.

My options were "Apple Extended USB Keyboard" and just "Apple Keyboard". The latter being the aluminium one, the other being the black keyed one (I guessed wrong the first time).

Given that the OP has indicated the entire reason for doing this is to be legal with his software licenses, and using Snow Leopard standard in a VM is against the software license, it doesn't make too much sense...

Besides, as I said, the VM has no graphics card support. If you're going to be dedicating a VM to reading email, it seems far far far easier to just get a machine for reading email. You could even pick up a used machine for $100 for that.

Yeah, using Snow Leopard standard is against the EULA - not that it's valid in a lot of countries though.

Using the combination like I tested out a couple of posts back would cost no more than the license for VMWare Fusion and wouldn't break the EULA if that's really something you're worried about. It's not that hard to set up, took me about five minutes (although I did already have a Linux VMWare install, a second user setup and fast user switching already enabled).

Of course having another computer is going to be far less hassle and provided all you need it for is email etc then yes a cheap second/third hand computer will do the task for you. I could see something like this setup being useful in say a startup company requiring two or three people to use expensive non-3D intensive software that doesn't burn the CPU all the time. As niche as that might be, it could prove useful to someone one day - software like Matlab and other development packages etc are very expensive and using a setup like this could make a small cash poor startup to buy one license and share it amongst several users on one system rather than just pirating the darned thing.
 
So they can all do their 3-D modelling work using a command shell? :D

Most of mine is (NAMD, DOCK, nwchem.... all remote to linux clusters, I work primarily in a shell) Now post-process display work, that's another matter :p

Makes sense.

VMware Fusion does makes it easy to select USB devices.
