Assuming you actually get them in sync to begin with, you're going to
discover that different machines will slowly drift out of sync with one
another due to the soundcard's onboard clocks all being slightly off
with respect to one another (and not even consistently out of spec, you
can expect them to change with temperature and for no reason at all).

So if you really expect multiple machines to _stay_ synchronized,
you'd have to constantly be communicating among them and somehow be
correcting the time slips that occur.  However, you're never going to
get within a certain margin of error, so I'd guess you will always have
funny phase issues if you can hear different machines from one place.
