It's Linux only.  There is no external documentation to reference it so it's 
probably more likely to change than most APIs.  But I don't see any changes 
in sight.

I was thinking of a debugging aid.  On the other hand, if it solves some of 
the privilege problems, it might be useful.

How well do USB devices work with gpsd on non-Linux systems when they get 
plugged/unplugged on the fly?

These are my opinions.  I hate spam.
