After much pain and getting my own, almost local, yet external dedicated server set up with root permissions, I was easily able to set up icecast in an afternoon and broacast my foobar2k player to it with ease.
I have an end-point set up, it uses a simple .ogg file output, or with M3U, XSPF or VCLT extensions beyond that (because platform support I guess). I could play the ogg in my browser with ease, M3u asked for a desktop media client etc. It had around 2-3 seconds of delay (server is 8ms RTT)
If this goes ahead, which I would like to see it, it might be easier to incorperate this into regular audio streams that might be used in the game, like soundcloud. However, it should have a different permission set, as streamed content is dynamic, administrators might not want to accept this form of media, only predetermined ones, such as the soundcloud, which have durations and titles etc.
