I'd like to be able to stream music, realtime, to a friend. Not in my LAN, but over the internet. I've done a lot of research on how to do this, one option was setting up a shoutcast server, but that isn't realtime as far as I know. VLC allows streaming, but again, this is not realtime.
I can't imagine this being so hard to do. I did a lot of research, and the "best" solution I could find was to use teamspeak with a music player plugin. It would be soo much more convenient though if I could just open rythmbox and start a stream, in which someone else could join and listen.
