Multiple-computer setup and license/cost impact

[grengama]

Hi all -- I'm seriously considering a switch to Pro Tools, but have a question on pricing and licensing for my multiple computer setup.

I do most of my engineering/mixing/production on my iMac, but due to the way my recording environment is set up (different rooms), I need to record most of my tracks on my Dell laptop.

Do I need to buy two licenses so that I can install Pro Tools on my mac and pc? Or does the license agreement allow me to install on both for the same price?

Many thanks for the help.
