Just looking around I came across /Badaboom /on Windows, a commercial
product, and a comparison of it on Anandtech:
    http://www.anandtech.com/show/2586/5

Kind of shows that for average Graphics cards, its no better than an
average CPU.

I also came across a thread that the /x264/ project (look on
videolan.org) had someone spend some time on the idea (through /Anvil
Studios/), and they gave up.

Also a comment on whirlpool said:

    PS there is no doubt it will be useful for decoding (which is what
    Cyberlink, et al are using it for), but for encoding you have to
    realise encoding is not a completely "parallel" process (in other
    words, at some point, 500 GPU/CPU's won't be any faster then
    100GPU/CPU's), current macroblock data relying on previous
    macroblock data, etc

And there were comments from an Intel engineer saying something similar
- its not truly parallel because some parts of the scene being
compressed depend upon other parts. But of course, Intel want to sell
another CPU... :)

Hm.
