Is it just a coincidence that Skype changed their AUP last week, requesting a license to all content transmitted via Skype (point 5.7 of their legalese)? That ought to scare some people away. To Wire?
I don't see that Skype get a license to the content, only that you should have the rights to distribute it (http://www.skype.com/en/legal/tou-usa/#5), and that they have the right to "take it down" if they feel like it.
