PS: A possible attempt to enable inside 'horizon border travelling' (far future) could be to add another Descriptor 'SuperpeerInfo': A super peer sends this message e.g. once an hour to all hosts in the horizon (high TTL) and tells that he is available and how big he is (how many servants connected). Every client can collect those messages and then:

a) hop within the horizon
b) avoid to be double connected within the same local horizon (it must not happen that you connect two big super peers within a local horizon and create identical traffic)
c) find new super peers very fast when one drops! (important for modem users)

Hmm, completely nuts what I'm saying?
