When I was still working at a large corporation, I built an internal "social" radio station using Icecast2. I'd broadcast my favorite music like Pink Floyd and Radiohead to my coworkers via a simple Rails web app, and we'd chat about music, work, and everything in between on the same web app. That was a long time ago, and I no longer have that environment (a big company with lots of similar-minded young people), but live-streaming music with friends will always be a soft spot in my heart.

Are there different solutions, different protocols, ideally supported by browser in some simple manner? Is streaming over websocket possible?
