Agreed. The lack of standards around this makes it very challenging and the implementation will be against a constantly moving target. We all know how this ends. :)

But it can also open the door further(not that it cannot now) to have 1password team become central password store for your production environment. I can envision a 1password agent (with hsm support maybe) running on a machine to provide processes with required passwords/keys as a way to eliminate the need to store passwords on disk. If the box gets compromised, changing the password in one central location so that others pick it up can be convenient.

food for thought. :)
