My bell says images and video (and also mp3, sure =). Although I don't know
which algorithm is used in most of these formats. Fourier or Huffman.
The huffman encoding in the libmoto and libmass is quite slow (read not really
optimized). I'm still pretty sure that some people in IBM would be able to help
us, given their work for Linux on the RS/6000.
Anybody's got contacts in IBM ?
