Sounds good to define and document identity and authentication 
separately. Unfortunately that work is only in draft from which 
explicitly discourages promotion :-/

BTW https://dvcs.w3.org/hg/WebID/raw-file/tip/spec/identity-respec.html 
has a typo: "Tim Bernsers Lee".

I meant possibly largest *PGP-based* WoT.  I did not mean to start a 
pissing contest :-P

Uhm, I missed your answer to the question.

We share that dream, you and I.  Challenge here is not the dream, but 
how relevant that dream is for our friends that are not dreaming that 
same dream.

Debian already has PGP-based WoT.  So question remains: how is WebID 
relevant for *Debian*?

Yup. Perhaps you noticed that the email thread that I referred to in my 
initial post here links back to that very conversation you had with 
Daniel at the FreedomBox list.  I was happy you got involved there!

My remark above was for others here who might not know Daniel and Russ 
that well. :-)

Fully agree.
