I did a little write up of the options that I think are most likely
solutions for issue #44:
  https://martinthomson.github.io/webpush-vapid/

(Submission as an I-D is imminent.)

All the relevant considerations are covered in the draft.  I started
out by describing a single option, but realized that addressing the
alternatives was probably wise.  In doing so, I think that some
combination of alternatives might not be as crazy as I first thought.

Some are clearly less good.  In particular, request signing has been
proposed, but I think that putting a signature validation on the
critical path is not a great idea.  The other options are much better
in this regard.
