I believe the ISBoxer remark is because they are running on a single system while you are running on two systems. Keyclone is one of the easiest the license per system seems a bit daunting, but its for life... Just look at the price of a pizza or something and decide not to get one one week and POOF, no worries about the $40 for keyclone which doesnt go bad if you leave it out for 2 days on the counter
