I only know for sure its planned use for SBAS Authentication.  So 
receivers can put trust into GNSS messaging.

I hear soft talk of uses in NORM.  Maybe some of those users will 
devulge enough information that we can reference that.

There are a number proposals for its use in ADS-B.  I am working on 
figuring out which to use in my ADS-B proposal....

I would like to think that we will make enough traffic here to draw them in.

It will tend not to be.  Each use will have its own hash size support 
and key reveal protocol.  Of course each hash will have its own 
construction.  Thus the rfc has to be general enough with good use cases 
in appendices to help potential users.

I was aware of it then.  It was in msec around that time already.  I 
think...

Briscoe was really pushing it.  At least in hall talks.

I probably had conversations with other 4082 authors back then.
