@jmar777, do you mind posting a real-world example of how you used it,
and why it was better than traditional auth-auth? Perhaps if I saw a
real case of, "here was the service we were building, if we did auth/
auth we would have to do X-Y-Z in the following way, if we did
capabilities we would do A-B-C in the following way, so here is what
we did with cap and why it was better," I might get a better grasp of
its usefulness.
