I've also thought of something like this but slightly different.
i thougt that the users could write add a description to a file and the gnutella client exchange discriptions related to that file so that after some time every body get's every bodies description or somehow discuss about that file. who does this sound?

your idea is great but where do the news will be saved? i mean when i have some news on my pc and go offline. or are you thinking of multiple copies of the same posted news on more than one computer? i like to know more about it.

some suggestion : if you are a good programmer write a patch for the opensource gnucleus and the swabby (author) will add it . i know him he's fun i'm making icons for that programm
