I agree, and would suggest that almost every element other than the 
abstract flow be up for discussion, this is a new protocol and we must 
consider all potential avenues, the strengths and weaknesses of each, 
then agree on a set of design trade-offs from which the final protocol 
will be born.

this is indeed an assumption,
  - is anything published?
  - is their a list of friends?
  - is the list of friends split in to grouped lists?
  - list(s) are pointed to (acl controlled resource(s)) or in the 
returned data after a dereferencing action on a webid uri?

indeed, should a users list of friends (if there is one) even be 
considered, are not the inbound links from other sources more valuable 
here?

is any of this part of WebID, or merely related? are these to be 
considered as design considerations and use cases for WebID separate 
to the protocol or core requirements?

and that's if RDF is returned..?

yes, every element of the protocol and flow thus far.

All we can say for certain, roughly, is that we need encryption over 
the wire, and to assert ownership/writership of a URI (name).

Best,
