no mIRC is used for filetrading but most members here (myself included) frown upon illegal filetrading. To send files to and from friends you dont need a complex p2p style system. The only reason for adding such abilities would be to swap music/games/movies/software etc.. wich is illegal. If there were another purpose (that cant already be done with standard dcc) then perhaps it would hold merit but in this case no.
