Festival of answers elided...

I've pretty much dumped ftp in favor of http.

And ftp with users and passwords are right out (I did
get skey and chall/response patches into wu-ftpd in
1995 or so).

I can require logins (over SSL with clear passwords) and offer
downloads.  modbandwidth or altq  handle usage limits  (someone
connects 11 times, it's just as fast as 1 time).

I'm willing to let ftp just die.
