I did some checking on the family pack license. I found that for both Panther and Tiger there is a single sheet of paper which is an addendum to the regular license; this is where it states that you may install the OS on up to 5 machines.

Ah.. for god sake, I just found it. buried between the software coupon and Applecare Service and Support Guide.
Why the hell did not the apple store tell me to look for that...

Thanks,

Too low tech a solution? ;)

Perhaps we should just be grateful that Apple does not annoy their customers with "online activation" and other silly things and cut them some slack with the hard-to-find license.

It's not like one of those black helicopters is about to land on your lawn, the guys on board kicking your door and taking you with them should you be unable to produce appropriate license documentation ;) .

Black could mean it is an Apple-stealth chopper!
