mybe a little bit off the topic. but any thoughts from this list?

but all in all, what ssl accomplishes can be done by ssh and what ssh accomplishes can be done by ssl. it seems to me that this is just another example of complicities (confuses) created by human.

SSH is a specific protocol designed for remote login (though you can do lots of other things with it). SSL a more generic protocol for secure communications. You could write applications that do the same thing as the ssh/sshd-applications using SSL as protocol. I have not seen applications other than ssh/scp/sftp using the SSH protocol, though I think they may be possible to realise.

Hope it helps.

IMHO the main difference if you want to develop new applications is the existence of such a great and widely used API for SSL, for which I don't know a counterpart for the SSH-protocol... ;) If you want to go into details of security and usefulness, I guess it's easy to start flame wars.
