I've got a write-up about that on my plain old - non encrypted - blog site:
That page describes how the simplified user interfaces works from the
end-user perspective, ie, creating an account, logging in and out,
selecting among multiple accounts. It goes into private messages between
clients (although with the site as delivery vehicle).
We can separate identity from transport, Ie, we use the accounts at this
dating site to authenticate a ZRTP stream between two people directly.

Please let me know if things are still hazy.
