My brother in law founded a company and designed a product called JamLink. It's a small networking hardware device that makes real-time, multi-location musical jamming possible, eliminating the latency issues that would normally plague such an attempt. For the SF World Music Festival he recorded a video of himself (on drums) and three world music musicians, well, jamming.
The other musicians are:
Imamyar Hasanov, Pezham Akhavass, and Anuradha Sridhar
I wish the video could display an image, given how nice pictures look here and that Ello can handle animated GIFs, but oh well, they say it's "coming soon".
