Using same copy of office on two different macbooks

My dad has got a macbook and recently installed Microsoft Office 2008 home and student edition. Im am getting a macbook soon too and will also want office on it. Is there any way of getting away with using the same copy on my macbook, or will i have to buy another copy?

Cheers in advance,

You'll need a license for each machine it's used on. Some apps allow for use on a workstation and portable (as long as use is not simultaneous) but Office is not one of those that I am aware of.
