Do you run IMAP over the POP port just because the function of both is
to some extend similar??

We are talking here about a new protocol named netconf which uses ssh
purely as a mechanism to achieve cheap security. So it seems just
natural to give the new protocol its own port number.

The way we use ssh is similar to using TLS. And IMAP over TLS and SMTP
over TLS still use the IMAP and the SMTP ports, not a TLS port number.

Unless I completely misunderstand the layering we are doing, I would
argue for netconf port number just for purely architectural reasons.

[I realize that in the "run everything over HTTP world", people look
 at this issue differently and netconf over SOAP might end up on port
 80, but this we probably can't fix anymore.]
