Not a good solution amongst any of that it seems...  Adding OpenSSH
would increase the image size dramatically.  Even a small ssh server
like dropbear adds around a couple meg.

/usr/ports/security/dropbear might be helpful.  From pkg-descr:
-----
Dropbear is an SSH 2 server, designed to be usable in small memory environments.
It supports:

        * Main features of SSH 2 protocol
        * Implements X11 forwarding, and authentication-agent forwarding
        for OpenSSH clients
        * Compatible with OpenSSH ~/.ssh/authorized_keys public key
        authentication

Someone has already integrated this into m0n0wall.

I'm not a programmer, but hopefully that might help you a little.
