Sometimes not a nice one <g>.  I've been doing that, and a straight
'just' intonation produces some definite nasties when the music changes
key.

Yes, I was ignoring harmonics particularly.  Notes more than an octave
apart do interact, but weakly (assuming relaively pure tones; something
with lots of harmonics will of course interact much further away).

A problem I've found with additive synthesis is that if I have two
unsynchronised sound sources at the same frequency (two organ pipes, for
instance) then depending on the phase difference I get strong
cancellation, far more than in a Real Life system.  The only way round
that I've found is to use a "spacial simulator" (lots of delay, reverb
and echo with each note source being in a different 'place').  Which
gets close to being part of a "universe simulator" and very slow...
