A Gnutella client is both a server and a client, so you would have to break part of it out into a server and that would just add more problems to what is already a complicated thing to do. You could have two things but most people want to know the "server" goes down when you quit the client, and the client shows all the server data plus the client data. It's not really a dedicated server.

You have source code, why not try breaking it apart and see how it goes?

I don't know why this is here in this section, can someone please move this to "general gnutella"? Thanks
