Some may argue the fact that it is limited to the act of authorizing and installing which prevents the simple distribution of the application (if copying *.app doesn't work). But, this is even worse in a "re-distribution" kind of way - people who bought the software, can now leverage their account to resell the applications at a lower cost - the customer just needs to temporarily provide the computer for distribution of the apps/games. I personally know of this KIND of thing happening, and their customers are delighted at their service.
