It's not clear that it _is_ feasible in any interesting sense.
The SPUs are essentially numeric vector engines. They have 128
registers, each 128 bits wide; loads are only 128 bits (16 bytes)
and stores are only 128 bits (16 bytes). Memory is byte addressed
and addresses are 32 bits, but the 2009 manual talks about 256 kB.
One could imagine SPU _nodes_ doing vector crunching that Erlang
processes running on the PPU communicated with as if Erlang. But
Erlang would not be the language of choice for programming SPUs.
(An APL dialect would be ideal, or Fortran 95.)
