I've done some searching around and couldn't find the answers to these. I apologize if I am asking typical newb questions.

1. Other Mac users can see my current iTunes song playing, but I can't get AIM users on PC to see it. Any way?

2. I've been able to send files to other Mac users through iChat by dragging and dropping, but I get an error when I try to send files to AIM users on PCs. Is it possible?
