You are right this isn't a phone post. And no, that is violating the terms of the license. The FBI will raid your house within 5 minutes of installation.
a) This is not the appropriate forum for your question
b) Installing on more than one machine with a single user license violates the terms of the license (EULA)
With that said, there are no measures in place to prevent you from installing it on as many machines as you want and, no, Apple can't tell.
Posting it in the iPhone forum was obviously a strategic move to get a fast response. However, OP, the other forums are visited too, and you likely would have gotten the response you needed with jeopardizing the integrity of the forum. It is almost certain this thread will be moved anyway.
OK. You know it isn't iPhone related, but insist on posting it here anyway? You've been here for nearly a year you should know better. I move for a mod to ban you for a week for deliberately posting in the wrong forum.
