Hello Dima,
I have looked at what SIMD assembly on the Cell processor would look
like.  It is somewhat not as good as you would think from looking at the
processor specs.  I was looking at it from the perspective of porting
x264 actually, since at the time (before quad Core2 Duo/Woodcrest
processors) it looked very promising.  Now not so much, I'd rather have
2x4 Woodcrests than 8 SPU's any time.
There have been other people who are interested (Guillaume Poirier, you
reading this? ;) but my sense is nothing will happen without someone
contributing hardware and money.
