>The EULA for the retail version of Office 97 allows the user to install the software on a second (portable) computer. Has this has changed in Office 2000 Retail version (or XP, for that matter)?

Apparently I didn't read far enough down in the Office XP EULA:

"You may make a second copy of the Software Product and install it on a portable Device for the exclusive use of the person who is the primary user of the first copy of the Software Product."

Mea culpa.
