Try typing this at the mac client.

$'xscreensaver -no-splash &
$xscreensaver-command -lock &

Let me know if this works.

I agree this would be a cool feature. I thought about adding this
before 0.2. But I was hesitant because it means modifying/playing
around with the default k12ltsp setup (considering all clients have to
run a type of vnc server ( x11vnc) and also enable some local app
support and editing lts.conf ). I'll take a closer look at this but I
still feel broadcasting is more useful than monitoring/taking control.
Now that I got rid of the xhost issue, installing fl_tt does not
modify a standard k12ltsp setup. The only optional modification is if
you want non superusers (say teachers) to run fl_tt by adding a
specific group to sudo.
