You can unlock with:
gnome-screensaver-command --deactivate
You can do all this remotely (perhaps from the cafe owner's PC) with
something like (untested):
system ("ssh client-pc-name DISPLAY=:0 gnome-screensaver-command --lock");
system ("ssh client-pc-name DISPLAY=:0 gnome-screensaver-command
--deactivate");
I guess you'd need to do the ssh as the guest user.
