A couple of comments, questions on this thread...

Doc, have you tried multiple TripleHead2Go's on a machine with dual 
output on a single card or with on a machine machine with 2 graphics 
cards? When I was looking at this the Matrox docs that I read stated 
that one of these combinations does not work. I think it was the dual 
output on single card hooked up to two TripleHead2Go's.

Also, related to Chris's previous post. For those that have done this 
(Chris?) how do you find the performance of these cards pushing this 
many pixels, especially when pushing live video to the displays? This 
would be interesting to know if anyone is experimenting with this, as 
one could imagine many possible bottlenecks...
