Works great for me too!  Very nice!

Possible minor problem if a user can rlogin into the PI.  Only one [lockscreen]
process at a time is active.  If a remote user starts [lockscreen], then it
seizes the monitor display.  (If a [lockscreen] process was already running, it
is killed.)  Now to unlock the screen you need the remote user's password.
(This also means any valid remote user can unlock the screen.)
