JP, I giggled up the same incantations, but they didn't work. For some reason
when I tried to start "DISPLAY=:0.0 /usr/lib/vino/vino-server" over the SSH
connection, it wouldn't work. Once I did "xhost +" from a root shell to worked.

When connecting from Mac OS X using the built-in VNC, you want to enable
the password [1] and set the password [2]

[1] gconftool-2 --set --type=bool /desktop/gnome/remote_access/prompt_enabled false
[1] gconftool-2 --type string --set /desktop/gnome/remote_access/authentication_methods vnc

[2] gconftool-2 --type string --set /desktop/gnome/remote_access/vnc_password $(echo -n 'password'| base64)

Even with VNC access, the bluetooth keyboard setup still isn't working. :(
