The activation key is based on the serial number of the PIX, and the serial number of the PIX is on the flash card. theoretically if you take the flash card out of one PIX and put it in another that new PIX *should* have the same serial number as the old one. Again, theoretically you could then use the same activation key off the old PIX on the new PIX and get the same features, provided the hardware (PIX model) was exactly the same.
I say "theoretically" only because I've never actually done it, but it should work.
