Well, I'm sure there's plenty that can be offloaded to the GPU (and
Google will give you a starter for 10 with h264 offload) but I'm not
sure CUDA is the way I'd go. It's specific to Nvidia hardware (and top
end at that) and it's not exactly a standard. Before I'd invest a
large amout of time in working with something like this, I'd llike it
to be a portable standard that doesn't require a special version of
the driver to run.

What's more, a lot of the power (but maybe not as flexible) can be
accessed through opengl already.
