Q: How many computers can I install Apple Motion on?

We have 4 apple computers in my family and would prefer to be able to install Motion on all of them but, I could live with installing it on 2. I am going to purchase Motion tomorrow. Can I instal on 2 computers?

I anticipate moving back and forth between laptop and desktop often. Currently, I plan to only have FCP on my desktop. But, I need motion on that desktop and a laptop.

My worry is that there may be some order in which Motion should be installed on these 2 computers. Or does Motion software and license operate completely independently of FCP software and license?

thanks...THANKS!!!
