So as I understand it, if there was a popular movie shared via dat and people were sharing it (the key would have to be publicly known for people to discover it at all), it would be trivial for the MPAA to snoop and see what IPs were downloading it, just like torrents now. Is that correct? Would those snoopers be able to prove who is sharing and who is downloading?
