Let's say I want to start listening to an Internet radio station, or any kind of webstream (using any codec) by pointing to an entry in a directory that's updated by RSS. The pointing could be with a Web client, or (better yet, to keep the concept simple and not locked into anybody's client) from a command line.

Is there any way of doing that yet?

[Later...] Dougresponds. AlsoLucasandJay. Great stuff. What I'm hinting toward here is the idea that we're not too far away from having a something like real infrastructure here. You know. NEA stuff on which a whole new form of radio and TV can be built. An industry, even. One not nannied by the FCC. Or anybody.
