FoxyTunes lets you control your media player from your internet browser. Works with IE and Firefox. Among many others support for iTunes & Foobar. If you do a lot of work in front of a computer like I do, you'll probably appreciate it.
Wow! This is a great app, mchale. Thanks for the link.
You can use any VNC package to do even better: control your remote (music server) desktop from any PC.
So, run Foobar on the remote in full screen and open a VNC window on the PC to see the entire Foobar screen. Of course, you can control all its functions.
Search for RealVNC or UltraVNC.
I have a Mac. If they had Foobar for Mac, I'd try it.
