As far as I understand the concept, it relys on ultrapeers having a very fast connection. In contrast to the "millions" of normal cable/DSL-users these can only be a few T1-luckys...

Is it really sensible to rely a peer2peer-Network on relatively small number on T1-People. Shouldn't the concept rather base on

1) normal Cable/DSL-users
2) add host-caching to the ones with a big upstream
3) provide ultrapeers to the big connection people
4) use all ways of connecting...if theres an ultrapeer, fine, if not, then continue as previously..

Please let me know, what you think about my (probably unqualified) thoughts !
