Interesting... I've heard similar concerns about the supernode issue, but, at least according to page 3 of Skype's network administrator's guide available at http://www.skype.com/security/ , no PC that is behind a NAT device or firewall can become a supernode because there is no way for them to be reached from the outside. Assuming this is correct, this would eliminate the supernode issue for almost all corporations out there. (Not to say there aren't *other* issues...)

That is true, it was verified by the Columbia University study as well. However, there are still lots of companies with public IP address space that I'm aware of.
