[Discuss] suggestions for low latency Internet audio conferencing software suitable for performing music?

[bogstad at pobox.com (Bill Bogstad)]

So lots of people are switching to virtual meetings via video
conferencing for many activities.
Whether proprietary (paid or free sample) or open source, they seem to
assume people taking turns talking to each other.   This model works
very poorly for people trying to play/sing music together due to
latency.   Obviously software can't eliminate the latency caused by
the network itself, but if you are trying to do this in a metropolitan
area among people who normally meet in person, it seems like it might
be possible.  I've done some Google searching for both free and
commercial software to do this and haven't found anything with the
ease of use/low cost that amateurs would want.  Any suggestions?
Depending on hardware/software what kind of latency can you get from
VOIP systems?

Thanks,
