Hi Chris,

You are right, it is a VNC server called vino-server, and you can
change the default port.

- Open up gconf-editor (Alt+F2, run gconf-editor).
- Browse to the key /desktop/gnome/remote_access/use_alternative_port
and check the checkbox.
- Modify the value of the alternative_port key.
- Restart vino with the remote desktop config dialog.

There is also a key "require_encryption", which you can check to allow
only TLS-encrypted connections into the server. I don't know of any
VNC clients offhand that support TLS encryption, however.

It may be easier though, to keep the existing port on VNC/vino, and
specify on your friends route to forward router connections, port 6789
to machine, port 5900 (default VNC port).
