That's right, you can't have a reliable check for the machine. But what 
you can do, and I would argue you should do, is check for a valid IDE 
license. So the rule could be:

a standalone built with Personal Edition will check whether the machine  
has a valid licensed copy of the IDE on it
If there is no IDE, then you get the 10 second start-up screen.
If there is a valid IDE, you get no start-up screen (or maybe a 1-second 
start-up)

That way, anyone with the Personal Edition can build and run on (all) 
their own machines without being bothered.
