There is a rdev that was recently posted to c.b.m or at sumex called
'Who's there' that displays all objects on a network. It displays all of
my XPress users (XPress is copy protected in this method), so it is
possible to see who's using your copy...

FOr what its worth, I have 1 copy of XPress that's liscenced for 15
users. It checks the network for more than 15 copies of itself at
startup. Since I don't have to deal with 15 serial numbers, I really
don't mind this kind of copy protection....
