Out of interest, is it possible to set up an anonymous service with SSH? Or would it rely on configuring an SSH server to accept any user-provided credentials?

The public NetHack server at alt.org has an SSH interface alongside the telnet interface. Try

ssh [e-mail]

It works properly with no password. It would be cool if Wikimedia would set up a similar thing for this service.

Patches welcome!
