I call this a plug in but I'm not so sure that's what it really is.
The software links to different sites for music, video etc than routes it with a single click. I think as long as you'll be able to set output devices in preferences, this should be pretty nice.
Unfortunately, it's and IE compatible beta so far so I haven't gotten a chance to take it for a spin. Firefox compatibility is in development.
Check out the video tutorial (ad).
