I'm aware of the distance to the speaker issue. I was wondering mainly
about network latency. I ran a test using icecast2 to stream to a
couple of machines, and there was a pretty big time difference (maybe
half a second). I was using one old laptop, though, so I'm not sure if
the delay was due to network latency or due to slow processor and/or bus
speed of the old laptop.
