If K/M shut down there'll be no way to create supernodes to catolog the location of all the files, but if someone comes up with a search engine for port 1214, now that would be pretty cool. no record of down/uploads for the record industry to follow.

fyi, bearshare works the same way, on port 6000 something, i forget the exact port number, but you can find it in some K/A users shared dir.
