Ah, I see.  I was looking at this from the wrong side.

Understood.  This is mostly about providing a development/testing 
environment.  And if your standard calls out use of OCSP, then you 
really should include that in testing.  I am getting ready to focus on 
the IETF SIngapore hackathon...

I would actually really like to have a SIMPLE OCSP responder.  But so 
far have not found one.  freeIPA has one buried within it, but that is 
too disruptive to install unless you buy into freeIPA.
