[RC5] [Announcement] Beta client for the PlayStation 3

No kidding! Let's see how much ground it starts to accumulate in the
overall stats. I was wondering about the code architecture, since the 
SPE are floating point processors, apparently. How does this fit in w/
the RC5 computations? Can you give a little bit more details?

Cheers, and regards.

Well, Cell is already #4 for yesterdays CPU stats:

There's one main (PPE) core in the cell and 8 additional SPEs. In PS3s,
only 7 of the SPEs are available, and when running under non-native OSes
the hypervisor uses one, so that leaves 6 available to dnetc.
