We see the same issues in GStreamer. It really is non-trivial.

http://mirror.fluendo.com:8800 should always be running. If not, feel
free to poke me. I'll probably set up a second one as well that just
generates a feed instead of using a device, which will have even more
chance of always being online.

Personally, I'd already be happy if it could play a non-chained network
stream. I understand how chaining is important for icecast, but I
personally like the one-chain approach more. Really, chaining oggs
together is just a bad way of doing a radio anyway, you want to have

yeah, .m3u should work. We'll probably make our server autogenerate
playlist files for the streams on the fly, as well as server a java
applet to see the stream.
Thanks again for the work !
