I don't want to use AppleTalk as my network layer, I use tcp/ip but I want to use the AFP ( I think it's called so ? ) as protocol, so if I use the connect to server command from the go menu in the finder and connect to localhost, my own server fakes an appletalk ( base on tcp/ip ) network. The server would map a ftp session to the finder. This would be a ftp client inside the finder.
