Are there real consequences to installing airparrot on as many computers as I want?

Are there any limitations as to how many machines I install air parrot on ? I know that the software agreement says that we are not supposed to. I don't care about that and never read it. How many machines can I install the software on with my key before the key doesn't work anymore ? Do not tell me about what the software agreement says. tell me if there is a trigger that will not allow the product to register.
