<plug>I've come up with something that might fit your requirements.

Technobabble: Users can create an cryptographic identity at the click of 
the mouse. With the verification methods I describe at the project site, 
it allows for man in the middle detection and prevention. His user agent 
takes care of all the crypto-details.

User sees: he creates an account at a (web) site by requesting an 
account name to be his. No need for email addresses, or identity 
validation that CA's do.

You can test it by downloading (or compiling) the user agent [2] and 
contact me at 'guidow@@dating.wtmnd.nl'. [3]

That's the problem, I'm facing, getting the initial seed planted.

I hope so too. The Tor datastream is easy to recognize amidst the sea of 
plain text connections.

<plug>with my plan, most connections are encrypted so those that need to 
rely on Tor have at least a better chance of hiding it.

Besides, with my protocol you really need Tor to protect your 
cryptographic identities against traffic analysis. Otherwise you're 
still fair game for the spooks.
