I wish I could say more. We're just getting into the territory where not only do i not have enough information about your exact needs in terms of implementation, but I don't know this stuff well enough to give you a suggestion and truly nail the details. As an example, the topic of wireless came up earlier in the thread, but it would require much more detail to figure out if something would work, then of course the potential to work doesn't mean it will work well at the required speeds without ever dropping connections. It sounds like you need a system that can grow over time with an intuitive interface on the client end so that they are able to see what you want them to see. I don't even know if they are supposed to be able to mark or make notes from there. It's still very abstract. I just don't know enough to suggest detailed options that I'm sure would meet your requirements.
 
I was a road race (running) timer for many years, so I've been around a lot of finish lines/awards ceremonies/parties.

In my time out there, I never saw anybody even attempt what you're talking about. Quick video feeds to a big monitor, sure. But it always seems to take a day or more for finish line photos to be posted on the web for purchase.

If you could get it running, it would be great. So good luck to you.

Just out of curiosity, what kind of events are you working?
 
His plan is doomed from the start. Forget about the computers/servers for a minute, he is really planning to display photography proofs on cheap monitors?

Bad idea. The colors, contrast and everything else is going to vary on each monitor, on different parts on any one monitor and will even change as the monitors heat up. You can't even properly calibrate most cheap monitors. And, he is going to be displaying these outside, like in full sunlight?

He needs to buy one 27" iMac and put a sun shade on it. Turn it into its own web server that displays a kiosk-like php site that generates web resolution versions of the images as he adds them in. Set up a scheduled job to check a folder for folders of images. Have it build a category based on the folder name and then import the images contained in that folder. All he would have to do is copy over the images into folders and the site does the rest. Should be easy for a php developer to build. It would run locally on the iMac so no internet connection needed.
