I'm on the road this week, so I don't really have a chance to play with the new iTunes, although the screen shots are promising. Here's my biggest question: I have a Mac at home and a PC at work. Both have tons of free hard drive space. Can I set up my work PC to sync MP3 files from my home machine (where I rip them) automatically? Can I get it to run in both directions? Automatically? Can I choose a subset to sync to my laptop? Can I see my full library from the road and change the subset I've got on my laptop?

I'm just dreaming here, but if even a subset of this works, it would be fantastically cool. Right now, I just move files around by hand, and keeping things in sync is a pain.
