Slightly off-topic, but imagine what you can do with a processor like this:

128 GFlops (douple precision), 20 times faster than todays processors, 8
vector units, available at the end of the year.

think you meet the synthesis capabilities they described
even on a bleeding edge athlon. the voice counts for just the
wavetable synthesis along are amazing, and you can run KARMA,
wavetable, subtractive, organ and one other synthesis method all at
the same time.
That might be a problem, even with heavily optimized SIMD code. :-)
After all, general purpose CPUs are optimized for dealing with the
"unpredictable" control flow of normal applications rather than the
kind of calculation/bandwidth ratios high end DSPs are designed for.
Not much to do with operating systems either way, although the only
potential solution - massive SMP - depends very much on IPC latency.
That said, I think you could get away with some CPUs in parallel for
the synthesis and some more CPUs in parallel for master effects and
mixdown. Shouldn't be much of a problem, since you can actually
process one sample at a time reliably (at least at 48 kHz and lower)
with RTAI or RTL on reasonably good hardware.
