I've got a lot to try.  But I'm fairly certain I can do very
well.  Additional latency from localhost networking is going to be tiny
beyond tiny, and unless I need yet more hardware, 4GHz should crunch
Zita's numbers very nicely.  I am currently thinking to run three soft
servers thus:

1.  Yoshimi 4x connected to non-mixer, and then triple Calf FX chain
(Compressor, Reverb, EQ)
2.  Calf-wrapped FluidSynth x7 or so connected to non-mixer, and then
triple Calf FX chain (Compressor, Reverb, EQ)
3.  Linuxsampler connected probably to single or double Calf FX (EQ at
least)

and then have all three streams to a hard server connected to the real
hardware and doing nothing else.  MIDI will be ALSA MIDI initially, I
may eventually get brave and try one of the MIDI-over-IP methods.
