hm and more barinstorming.

How about adding also country or toplevel-domain to the "SUPERPONG" descriptor (e.g. 'us', 'au', 'fr' ... or 'aol.com', 'swipnet.se')? It could be a good idea to connect to a superpeer located in the same country or at the same ISP. Gnutella causes a very high traffic for an ISP, using a local superpeer can reduce traffic for our ISPs... and so reducing costs... and so make high bandwith internet cheaper for us consuments.
