It's being worked on, mostly by Bovine, JT (the PS2 porter) and  
myself. We have a prototype running with assembly-optimized RC5-72  
SPE cores at ~24 Mkeys/s per SPE (of which there are 6 user-available  
SPEs in the Playstation 3, so about 144 Mkeys/s total on the SPEs  
alone). There are still some issues to solve, and an optimized PPE  
core must be written, since current PowerPC cores have abysmal  
performance (as expected). Currently I'm working inside IBM's Cell  
simulator, which is holding things back a bit (it takes almost a full  
day to run the benchmark suite that would normally take 16 seconds on  
real hardware). Having a shell account on a real PS3 running Linux  
would be a huge productivity booster -- so if anyone has the means to  
help, please contact me off-list. Cell blades would be equally welcome.

Note that at least initially, the client would only run under PS3  
Linux. We realize this is not ideal, but a native port to the PS3  
would require a Playstation 3 development kit which we don't have. If  
Sony or someone else were to provide us with a dev kit and sign the  
binaries, we would gladly port this to the native PS3 environment.
