Combination of screenblank and lockscreen?

[lwv27 at CAS.bitnet]

Does anyone know of a tool which combines screenblank and lockscreen?

What I would find useful would be a tool which would watch the system and
when it saw no user keyboard or mouse activity in a user defined set
period of time would lock the system, requiring a password to gain access
to the desktop again.

The trick is that the underlying windows must not be able to push
theirselves over top of the lock screen.  Likewise, a newly created window
must appear below the lockscreen.

The final nice touch would be if the locked screen could display the
output from various programs similar to the way the standard lockscreen
does it.
