[PD] open-ended video mixing

I want to build a program which takes a flexible number of videos and  
mixes them all to one output.  Basically, I want to be able to start  
and stop playing any video at any time and have everything mixed into  
one screen.

This is for a cafeteria that all of the walls and ceiling are covered  
in 50,000 LEDs.  Its not quite a video screen, since the pixels are  
3"/8cm square, but it should allow for some crazy stuff (more info  
later, as the project progresses).  All of these LEDs are mapping to  
a video-in.  The idea is that someone could make a video for one  
section of the cafeteria and it could be played at the same time as  
someone else's video for a different section.  Think of trying to  
curate a giant video frame by divvying out sections of the screen to  
a open-ended number of people.

(this doesn't have to happen in Pd, by the way, but it would be nice  
if it did).
