Hrmm.. According to:
http://www.secdev.org/conf/skype_BHEU06.handout.pdf

Skype does TCP if UDP attempts fail. However it appears to encode your
IP address in messages. Sort of defeats the purpose of Torifying it.
Probably the case with a lot of voice clients, unless you can find a
way to get them to not discover your IP...

I also find it unpossible that actual watermarking was used against
this fellow as opposed to simple IP tracking.
