I did look at it when you first made an announcement on this list.

I looked at it very briefly again today.

I am not sure you totally get rid of CAs. You seem to propose a CA for 
pseudonyms, freely available to arrange anonymous secure connections.

I don't have any particular opinion; I'm working on something different 
where a service provider adopts the "first party certification paradigm" 
for real user identities (or pseudonyms where the pseudonym owner can 
enroll a new PPKP public counterpart after grabbing the pseudonym).

Good luck with your client certificate experiments and best regards,
