Multicast the stream on the network and use the same amount of buffering
on every computer. Also, only use the multicasted stream, or you have to
delay the source to be in the correct time. The multicasted music will
be more in sync if all the listening computers are listening to the same
switch/hub.

You can also try normal streaming with , but you won't get as good
results as with multicasting.

(I can't recommend any software that is able to multicast, though)
