Yes, but it's a strategy only usable against BT devices.

Yes, that's possible, but only with devices used through client
software layer responsible for assignment and storage of such UID.

There are also Garmin devices which have accessible serial numbers
and solutions like used in (some?) Trimble units - user can
assign unique id, so is able to identify every unit from a set of
used in a team.

Unfortunately, I'm pretty GPS unit do not provide anything like
unique PRN codes used to identify GPS satellites.
