I don't think non-technical users need to ever see anything except
similar user interfaces as shown earlier in this thread.

You can transform an OpenPGP key fingerprint into a SAS-like string, if
that makes you feel better, and ask users to verify that. Hash the
OpenPGP fingerprint, truncate it and encode it using the same length and
characters as used by SAS today.
If you don't think that is acceptable, the challenge is yours to come up
with something better. The security industry have been trying for many
years... I'm not aware of any technology that is more secure and
simpler to use than TLS+OpenPGP with user-assisted fingerprint
verification, but I'd love to hear your counter-proposal.
Disclaimer: I haven't studied the ESession protocol.
