Yes, CRMF is how we'll eventually add user certificate support, but this 
is the easy part.

On the server side we need to add support for multiple certificate 
profiles (your above request issues a server cert for the user abradley).

We also need a way to manage a queue of requests. User certificates are 
a different beast from server certs and in many cases will require the 
intervention of a security officer, or some other 3rd party verification.
