The idea of FTP to use _two_ sockets for communication, and that the
second one is made from server to client, is completely idiotic. It
makes FTP difficult to handle. Passive mode is not much better - why
the hell "out of band data", if the underlying protocol is packet
based?

The two-socket-concept is not very good for SSL either. So I really
cannot see, why FTP or FTPs should be a good idea. Perhaps you can
explain that.

While FTPs is strange like FTP is, SFTP only has a common command set
in the common client software together with FTP. This is a good idea,
because people are used to deal with it, and don't need to learn some-
thing new. But the rest of the protocol is just SSH.

Of course, you can critizise SSH (as a matter of fact, I'm waiting for
yours or Casper's critics), but it is not as ugly as FTP.

Yours,
VB.
