Details on these, please? Since that was kind of what I was asking for in the OP :) 

I have found a couple on github: <> <>

(Blargh is right ( <>). Googling for this stuff is *hard*:)

And I *am* researching this for an enterprise that has strict access control requirements.

Not only are we expected to provide evidence of when users accessed systems and for
how long, we are also expected to show when access was requested and who approved it.

Simply trusting (mostly non-technical) users to do the right thing is never a good 
idea when auditors and compliance folks are involved.  

As far as an OpenSSH CA is concerned, I’m thinking of a model akin to the big X.509 CAs 
for enterprise users to obtain ssh authentication keys. If the keys are  never touched by human 
hands, so much the better.
