I, too, run a Skype supernode - completely unvoluntarily, barring the possibility of something hidden behind an asterisk in the EULA. Does anyone know if there is a way to "opt out" of this? Everytime I start skype up it makes a million connections to everywhere and without even having a call on the line my measly 2.5 mbps upstream is permanently choked.
Sorry, I should've mentioned that I'm an OS X user :)
With that said, I've had a look-see in Skype's .plist and its various Application Support files, but oddly there's nothing "grep'able" to be found anywhere...
