Skype Supernodes

James Enck, commenting on the ongoing banter between myself and Aswath on SkypeOut and SkypeIn gateways, notes that he has "long assumed that Skype has 'seeded' a number of its own supernodes globally from day one." The Baset and Schulzrinne Skype Protocol Analysis observed what they called "bootstrap supernodes" - seven IP addresses and port pairs that always showed up in the Skype Host Cache on the initial installation of the Skype Client. It's very reasonable to think that these bootstrap supernodes are run by Skype, supporting James's assumption.
