A girl instant messaged me last night on limewire (I have 1.7 I think) and we had a great time talking. I wasn't even sure I could message people. How do I instant message someone, and how do I find her again? I saved her ISP at the time. Would that help?

I'm not sure how to bring up a chat with window if you don't have a search result from that person. Saving the ISP (I assume you mean IP, like 12.34.56.78) should help but I don't know where to enter it. You could try connecting to the IP in the Connections panel, searching for something that would match, and right-click a search result for Chat With Host but this is ridiculously complicated for something that should be so simple. It seems like a chat with IP feature is missing.

This would be pretty damn easy really. All they would have to do is switch the http file transfer with a chat connection. That is all the limewire team did.

Then if we just create a seperate client that uses a different connection stream so we would have our own designated network for chatting rather then mixing up our bandwidth with the file transfer people.

Chat connections could be secure and verified based on simple PGP connections.

Search key word's and returns are simply unique userID's attached to a nickname.

That be the first working bones for the first decentralized instant messaging system? It could kill AIM and all the rest, if anyone has the balls to make it.
