Terms of DEVONthink license

Does the DT license allow for installation on a desktop machine and a notebook? I intend borrowing a friend’s iBook for a couple of weeks while I’m on holidays and would like to install and use DT during that period.

Also, my friend’s iBook has Mac OS 10.2.8 installed. Does DT 1.9.2 run under Mac OS 10.2.8? Or does it require a later version of Mac OS?
