Yeah, this loophole was already exploited by a number of companies who sold programs that did software-metering. For example, Company X had 500 employees who needed access to MS Office. Since all 500 didn't need access at the same time, they decided 100 copies would be enough. These 100 licenses would "float" between all 500 users. The metering software would keep track of all the licenses to make sure they only had 100 instances of it running at any one time. Of course, in the case of MS (and a lot of other companies), they've since removed this "loophole".
