Jitsi would fill almost the entire thing, with the exception of better voice/noise cancel, but mumble would be nice too. I don't need the text chat too much. What I currently use for music is that I have a basic icecast/shoutcast server on a VPS, I stream music from my machine to that server (butt client), and I have a simple radio HTML player (using amplitude.js to adapt it for live-streaming) on a webpage that my players listen to. It's great quality (basically same as listening to it myself on my own machine), but comes with some latency. The reason I do this is that, to make even more annoying, I don't stream music or use youtube much. I like to have my own music files, I also often have music that I edited, cut or processed a bit (like a nice cover of a video game track that I downloaded and applied some noise-reduction on, etc..). So yea on top of everything else I have to stream music from local files.

I'm a tech-person as well, but even just having to load a seperate web page for my HTML radio is something that I need to remind my players of, introduces potential technical issues, and I also need to load up a whole audio config on my machine every time. It's working pretty well so far tho, just wish I could get rid of the latency, or at least guaranty that all players and myself have the same latency and not have one player 2 minutes behind. Pause/Play on the players fixes that problem, but that kinda ruins the mood to have to make sure my players are hearing what i'm hearing.
