Using a Server Mini as a "MBP dock"

Currently I take my early 08' Macbook everywhere with me and at home hook it up to my FW 400 external/scratch disk and work from there.

I've been tempted to get the early 2011 13" MBP (I have a few important PPC applications) but want to know before I lock one in if it's possible to use the server Mini as a sort of docking station over Thunderbolt.

Say I'm working on a FCP7 project on the road and when I get home I can hook it up to the Mini and finish it from there with the two machines working as one?

Would such a thing work if the Server is running Lion and the MBP Snow Leopard?

I'd also like to use a 1920 x 1200 monitor as well, could I screen share the two as an extended desktop and use PPC applications?

You sure I couldn't share some resources between the two with stuff like QMaster or XGrid?

Honestly I have no idea what I'm talking about and thats why I'm asking.
I'm getting kinda tired of sitting around waiting for a free space at my campus' computer lab to use FC or whatever so I'd like to use a MBP to work on what I can there and plug it into a mini at home and finish there.

I suppose what I'm asking is if the Mini can be used as a cluster or whatever it's called to offload some work from the MBP? I know QMaster I think distributes the FC/Logic workload between multiple computers right?
