Maybe you could use both products on the same machine by changing the 
MATHEMATICA_BASE/MATHEMATICA_USERBASE environment variable when you 
switch from one to the other (and on initial installation).

I do agree about your complaint though, mathpass files are obviously 
encrypted, but it would be nice if in all other ways their behaviour was
