Sync music between desktop and phone over wireless?

[rexeast]

This may be a basic question, but is there a way to keep music synced over wireless between a Windows (Vista) desktop and a Windows Mobile (6.1) phone? (I tried searching this forum but didn't find anything with my search keywords.)

I am aware of Orb, but would prefer to transfer the media files themselves instead of always streaming. I had the idea of seeing if this could be done with Windows Live Mesh for WM, but wanted to see if there is another way.
