how about limewire use md5 and crc checking when downloading in a swarm fasion? when you download a file that is being swarmed, all hosts should check the md5 and crc of the file and send it, then limewire will pick the hosts that all match the same md5's (the majority of the hosts returning the same md5's will be picked). something of a smart-host checking.

this will definitley reduce the amount of riaa and mpaa fake files that they are pumping into the network(s) that they make to corrupt the swarm downloads (and individual files) because normally when i search the network for something that is rather popular (usually hosted by t3's) some files are genuine but the other hosts are "masking" as the real thing while only delivering fake content to screw up the swarm.

md5 is the way
