Oh I have no doubt it's compatible with the Gnutella network. Aside from a few wording changes, the protocol is darn near the same. It would be rather unusual, however, after taking the initiative to start their own network because of the proposed problems they see in the Gnutella network, that they would care to make sure their clients were still compatible with the Gnutella network. As of yet, there doesn't seem to be a bridge between the two networks and I'm sure the originators of the OpensourceP2P network would like to keep it that way. After all, bridging the two networks would once again open up their network to the problems they were seeking to avoid to begin with! So, in other words, it sounds to me like they're gone and not coming back. Hence my question as to why they're still continuing to use the Gnutella Forums as their forums as well.
