The issue a lot of the time is not necessary the legality of the files, but the fact that mIRC is not a file sharing program. It is not a KaZaa hybrid. I'm not going to go into a big tirade over it though. I was suspicious that the only reason people would connect to that many networks is to file share, which is precisely the reason that would deter me from wanting this included in mIRC. People that actually use mIRC to chat generally do not connect to 5+ networks.
