Its a possible solution, also you can split stuff with software and then send to separate render nodes (aka computers) that will deliver those to their screens (imagine each computer could have 2 screens), as cyrille pointed this things can be heavy when you aim for higher res.
In college we have a 12-projector array [1], it runs GL apps using openSG[2] cluster windows.
I'm really interested in seen that installation of yours come to life. Please share videos/photos of it running on those 10 screens!

The screens we are currently specing are 1080p, so each output should be able to do 1080. The idea is to have 10 contiguous screens all in a line show one Gem space. They can show up on the computer as contiguous or separate screens, that doesn't matter, I can handle the difference in Gem. I think it might be easier to have them show up as separate screens.
I can break it up across multiple computers if that's easier, I'm mostly trying to reduce the expense. I am just showing images, so not heavy on the CPU/GPU.

hello,
with things like doublehead2go, or triplehead2go :

you can easily have lot's of screen on 1 computer.
(downside is that the screen are only horizontal)
i made a 6 screen installation with a 400€ desktop having good performance.
(GPU was a NVIDIA 9600 or something : only use nvidia gpu on linux if you need good performance and are not afraid of proprietary driver).
but what is the resolution of the screen?
to have a screen disposition like this :
x x x
x x x
is less a problem than like this :
x x x x x x
The size of openGL windows is hardware limited. usually 4096x4096, but can go up to 8192x8192 with GPU having lot's of memory (go for 1go video Ram).

I am looking into doing a 10 screen installation using Pd/Gem. I'd like
to run it on as few computers as possible. Anyone have any
recommendations for Debian or Ubuntu setups that can have like many DVI
