Hola Carlos,

If you want to grant 10 licenses, create a table with 10 records. Whenever a user logs in, he grabs the first available record and locks it.

When 10 records are locked, no more users can grab a license and the program bounces them.

If any workstation crashes, its locked record is released.

This is the simplest way I've seen for implementing what you need, but I'm sure that someone can poke holes at it and/or come up with something more interesting.
