The video streams would be remixed in realtime and output via a single projector. Was wondering if anyone has played with the scenario and has some advice to offer?

Camera-wise I was looking at two solutions 1. four cameras go into a multiplexer and then I grab the four different quadrants from the video stream or 2. four firewire cards (might be too much of a brute force solution:) + might run into some interesting driver issues). Also, is there an advantage to having two boxes processing inputs and then sharing them over a network i.e. using more then one computer for this work?
i've been using up to 4 usb-cams (PS3 eye) in parallel with Gem at a
resolution of 640x480.
latest Gem (currently SVN-trunk, no release yet; on linux! i think on
OSX this has been covered with the QT API for ages), can also grab
streams from IIDC cameras (raw video over firewire), which might give
you a lot of streams in parallel, but i haven't tested using more than 1
camera (due to lack of hardware)
