Scripts run sim-side, audio streaming is entirely client side. You can't
really connect the two very easily.

I've hacked together a system, where my oddcastv2-xmms streaming source
uses the songchange plugin to call a python script that makes an XML-RPC
call to push the metadata to an in-world object.

Apparently there's another system about that apparently involves an
in-world script polling the streaming server directly over http. I
haven't gotten my hands on it so I don't know the details.

Really, I'd like to rework the streaming UI to be more than a couple
buttons and a slider on the bottom of the screen, I'd like to make it a
full floating window, which can display metadata and whatnot.

I'd also like to eliminate the property owner monopoly on streaming
music, what I'd really like to see is a "Radio Station" object that
could be freely passed around, and played in any location, much like a
landmarks and notecards.
