You can certainly get at the SPUs, which are definitely amazing 
hardware.  I don't think the PS3 will be usable for Linux gaming anytime 
soon (unless someone ports Mesa to the SPUs), but I do think that it is 
already very usable for scientific programming and other number 
crunching.  Even rendering, too, just not rendering to a display.  
Actually, I think that if someone modified the program in the right way, 
the PS3 would make an AWESOME asterisk box.

Basically, if you schedule it right, you can do four floating-point 
operation each clock cycle on each SPU.

I'm starting a series on programming the SPUs in assembly language 
pretty soon, and you'll be able to see exactly what it's capable of.  In 
fact, if anyone is willing to make helpful suggestions, I'd be willing 
to show them to a few people early on.
