Shareaza claims to support multiple networks, however in its most recent guise connection to gnutella has been less than satisfactory. In my experience at best I have been connected to only one G1 ultrapeer at a time for only short periods making the network unusable. Gnutella 2 may have the technological edge but just doesn't have the volume of content, edonkey is great if you have dsl/cable but for those of us with dial-up modems the queues are just to long. Having been away from Limewire for some time I'm glad to be back downloading lots of those luurvley gnutella files.
