Ninjam allows musicians to play music together through the Web using audio streaming. The Social Software Weblog calls it: Skype for musicians.

A short excerpt from the linked article:

It takes a rather unique approach to the ubiquitous latency problem involved in trying to keep multiple signals in sync: instead of trying to eradicate the latency, Ninjam actually enhances it, such that each musician is actually playing along with the previous intervals of everybody else. Creator Justin Frankel (developer of Winamp) says it takes some getting used to but becomes natural in time. I’m hoping to get a chance to try out some intercontinental jamming at the earliest opportunity, meself. The creative and collaborative potential here is pretty exciting, and this is only the beginning.
