It actually loads a browser extension to work, and its only compatible with your average desktop browser (Windows XP Firefox/IE).
I could be wrong, but I think I've heard it won't work with Safari, and I've never been able to get it working on my Linux box.
All things being considered, the fact that they made this so proprietary that people using some desktops can't get it working, its doubtful full WM support will happen anytime soon.

Only thing you could perhaps do is log in to your desktop using logmein pro or something that supports sound, and stream it remote-desktop style! I'm guessing quality would pretty much suck like this...
