Interesting Technology Review article.

A startup called eJamming claims to have solved some of the problems that have plagued musicians who jam together online. According to the company, its software, called eJamming AUDiiO, is able to let musicians collaborate in near real time with musicians halfway across the world. Additionally, the software simultaneously records each musician, combines and synchronizes his or her input, and creates files with CD-quality tracks, says Alan Glueckman, president and chairman of eJamming.

The main problems with remote jamming are bandwidth and network latency (the amount of time it takes a data packet to travel from source to destination). eJamming seems to have tackled the first with a new compression system, and the second by using P2P technology to put musicians in direct touch with one another rather than being linked through a server. Neat if it works.
