But why? The current Kademlia implementation built in eMule/aMule does exactly this. Primary data advertised is file name string, there is also a support for several meta fields. Transfer proto sucks, but I don't think it really matters in the case of ultra-rare content.

That `ultra-rare content`, eMule is mess if you need collection of files, ofc you can share ZIP but they get somehow repackaged too often. Torrents nicely group the stuff - it is kind of album.

I've dreamed of federated meta-client which mixes all available p2p networks in a wild and can download missing torrent part from eMule or Soulseek.
