Peer-to-peer (P2P) -- Dial Up -- model type BBS -- I SysOp-ed apart from running a regular BBS. In the 1990s. My BBS friends and I used to interact like that; Plus, it's my Remote Access Server too meaning I used to login on to my BBS from my work place and access files and all that and E-mail my friends or chat with 'em. Et Cetra.
