It would be cheaper to employ the same method used on some
lawnmowers and required on Jet Skis and Skidoos: a cable with a clip
worn by the rider. The rider falls off, the cable releases from the
vehicle, disengaging the throttle and cutting the engine. The boss
stands up, his entire infrastructure collapses, everyone's connections
are closed, and all PCs subsequently catch fire.
I fear this is the implementation needed to make "boss" see sense, however..
Realistically, a simple desktop-based application running in the
system tray (presuming Windows) would send a kill signal to a
predefined script to issue safe closing routines to the database
first, then any other systems he wants to close out. It could even
have simple options to poll if there's a screensaver activated, which
would initiate the process automatically, should he choose to be
extremely paranoid. The same could be automated to work in reverse,
to automatically bring the systems up, when the local desktop session
becomes active (from hibernation, logoff, or screensaver), or even
with an override ("Pause Sessions") by right-clicking the systray
icon.
The main problem here is in using a stateless protocol (HTTP) in a
stateful manner (with sessions), it makes this, technically, impossible.
That said, you could do this in a stateless manner quite easily by
giving the boss full control of granting and denying access, that way he
is always accountable (with his described nature, it might be good for
the buck to stop with him, rather than your code). I'd suggest having a
simple boolean flag, usersCanAccess and giving him a button to toggle
the flags state from true to false. Real life implementation could be an
empty file which is `touch`ed and `unlink`ed, php implementation being
an if(file_exists('boss_man_say_okay') ){ // let monkeys work } type
solution.
Best,
