Hi, Dan.

Really this is a great feature. I never connected into a machine via ssh
tunelled connection. So, some questions:

- Doesn't it need a password?
- The port parameter is the port of VNC or port of SSH?
- What about use the same api (vnc_display_open_host), just adding a
boolean parameter to indicate if the connection is via ssh or not?

Thanks,
