I'm not Stephen, and I don't play Stephen on teevee, but anything you 
can do with pre-shared keys, you
can do with with an asymmetric keying approach too. Pre-shared keys are 
pretty high touch form of enrollment,
after all. If you can get away with leap-of-faith kinds of enrollment, 
it is even easier IMO because you don't have
to remember messy and/or lousy keys/passphrases:

New Thingy: "I'm blah and want to enroll! my public key is blah-blah-blah"
Enroller: "Sure!" or "Nah, you look sketchy"
