I would pick up an old rackmount ethernet switch and use static ips. I imagine wireless would work, but you're asking for trouble if you don't get an industrial wifi router.
As for software, I'd echo using OpenFrameworks. The current version (0.8.0) now supports the RPI and there is an OMX video player class which can run with hardware acceleration. It would be simple to code a single, custom video player app that listens over OSC to start, stop, set frame position, etc. Said app would read from an xml file to know which video to load, so you don't have to hardcode anything. You will not be able to do this with PD alone on the RPI since, as mentioned before, GEM currently has no OPENGL ES support on the RPI. Email me if you guys need help/have a budget, although my timeframe is a little cramped right now.
