Well, it is also well known that on some 'other' p2p networks (non gnutella1) .. not naming any lol ... that due to their extra connections to hosts, others can spend ages sitting in queues for downloads. It's a sacrifice, one or the other, that people connect easily to hosts, or that they sit in queues for hours on end.

Also the sacrifice with multi-p2p network programs, is that when they are using multiple networks at same time, the uploads suffer on others. Shareaza's behaviour on Gnutella network has always been a problem in that regard, not uncommonly getting speeds of less than 1 KB/s from Shareaza hosts due to their upload bandwidth being spent on 'other' networks. (Or their upload slots being taken up of course.)

IMHO .. Ideally, such multi network programs should either (a) only connect to one network at a time, or (b) be forced to offer a minimum upload amount per network they are connected to.

Shareaza does have the ability to connect to only one network at a time, but not many users choose that option it appears. In so many ways Shareaza could be improved, as it is a good program. As I said, just IMHO.
