Is it possible to lock down WiFree so the person can't pay and uninstall it, only if he goes thru the Kehila?
I know you can get alerts and everything, I am talking in a case where this won't help.
I think i have a solution for you but ive never had a chance to try it (i need netfree to try to uninstall after making a lock on netfree service & files)
