It depends on the level of security we are wanting. The most secure
places I have been at always make sure there is a human in the loop,
and that human's events  are regularly and randomly audited. Even
having hardware tokens to generate things (we had a device that was
hooked in via a serial port so it did not need a kernel driver) for a
high level of CIA you may want a set of humans looking at it. However
it puts in a delay. We would put a 24 hour delay in getting/creating
certs for people which meant we had time to confirm that the person
really was supposed to get it etc..

If the delay and the fact that we aren't doing background checks on
applicants, we probably want to do a multi-tier level of creating
tokens. One set would be ones that people need to be vetted somehow
and have more keys to the kingdom. The other set would be for people
doing common work flow at the project.

I wonder if we can come up with some serial port key generator. I
think the design was a locked box where you keyed in the the master
number via itsy-bitty dipswitches.
