As far as I am concerned uploading C.Elegans was solved by Ferrée
( http://www.csi.uoregon.edu/members/ferree/publications.html ) in 1996 until
someone explains what's wrong with his solution. The fruit fly is orders of
magnitude more difficult (200,000 spiking neurons vs 302 graded signal
neurons). IMO it should be possible to emulate a fruit fly on a PC cluster of
20-100 processors.

ASCI White is most likely sufficient to emulate a Fruit Fly. Blue Gene (due
2004) should be sufficient to emulate a mouse. They are general purpose
computers. If the same effort would be put into a neuro machine then the
hardware side of emulating a human brain is likely in reach now. I am saying
most likely because we still don't know if neurons are way more complex as we
think they are (e.g. Penrose).
