There are tools which exist (I'd provide links to examples, but my 
google-fu is failing me tonight) which when given a compiled application 
(LiveCode standalones will work fine), will wrap it up in something 
which will control the number of simultaneous uses on a local network.

It might be a good solution in your case. Indeed, there are some 
organisations (such as universities) which actually use them themselves 
on the software they purchase in multi-user settings in order to ensure 
they can strictly conform to licensing requirements.

Hopefully someone else can find the right phrase to google to point you 
in the right direction!

Warmest Regards,

Mark.

P.S. Writing a system which you propose is perfectly possible - in 
LiveCode - the IDE does this (for example - although our solution is 
very specific and not general). However, it isn't an inconsiderable 
amount of work - particularly as users tend to get a little 'vexed' if 
the system breaks at any point (even for short periods!).
