I'm new here, but hopefully someone else might find this useful. I really liked PS3 Media Server, but as I generally use Ubuntu I wondered if it could be better integrated, specifically picking up on the Rhythmbox music database (as this will speed the setup for many users).
Anyway, with a bit of hacking and reading the source I got something working... hopefully the attached file should just work (assuming you're on something unix-ish and have Rhythmbox, if not it'll probably do nothing). There's loads of thing missing (album art for and sort ordering starters), but hopefully it'll work for someone...

update: there was a big bug in the first version, so I've fixed that (though there are still some issues)
