See the r-devel archives for August where Doug Bates started a thread

        [Rd] Compiling R for the Sony Playstation 3 with many posts.

The upshot,as I recall, is the he 'simply' installed Ubuntu on his PS3 in order to real software (read: Emacs, R) running on his 'dvd player' as he calls it.

There is a lot of interest in making R work on things like the Cell as well as in GPGPU frameworks, at least for subroutines and libraries (and I understand that some work is ongoing in that area). The main R thread will probably remain single-threaded 'forever'. Others may have more pertinent comments.
