Just a minor nit; PASV mode wasn't invented to deal with firewalls; if I 
recall correctly, it was part of the ftp spec early on, and its intended 
purpose was for server-to-server transfers. The "standard" ftp session 
had client1 teling server1, "send this file to client1". PASV was 
supposed to enable the client to tell server1, "send this file to server2".

I seem to recall a lot of early ftp client software didn't support the 
server-to-server capability, particularly on MacOS and PC platforms.
