This part I solved as follows. We don't work 24/7, but sometimes we need emergency maintenance. So, for several maintenance tasks, I create a file called "maintenance.tmp" in the shared directory. A Timer will check every 2 minutes, and if it finds this file, invoke the application object's OnQuit() method (using Visual Extend).
On application start, the program checks for this same file. If it exists, it will give a corresponding error message, and quit.
One potential problem is that the OnQuit() method might show a dialog (especially if there are pending changes), instead of quitting immediately. So far, it seems that this wasn't a problem in actual practice.
