Sorry that I come back to that. For me as non native English nruddock's explanation sounds a bit as if you can run more copies with a floating license than you have bought. You definitely can not (I have a floating license). You can only run as many copies of Infinite the same time as you have licenses. The benefit is that the license is "shifted" to another machine when you need it there.
