Dilema? Its not really a dilema alot more people are sharing now on gnutella than a year ago when there were those funny news articles predicting gnutella death within a few months. I think people worry too much about freeloaders.

Information is the only thing really needed. I say let users see whos sharing and whos not and if freeloading bothers them then they can manually abort all they want.

Swarming wont intergrate modem users supernodes will. Using a supernode a modem user can download/upload the same as they would on a centralized program like napster was. Swarming just makes downloads a little faster thats it. It wont help modem users if just that is added because modem users will still use most of their bandwidth on host connections.
