[Ndn-interest] NDN protocol principles: no privacy?

hmm - it seems like you and Tai-Lin are sort of conflating some things 
that are not necessarily entangled.

I think it would be good to make private communication the default - not 
the _only_ choice. I don't see how changing the default to 'private' 
does anything to compromise the network as a whole.

there may well be types of communication that _must_ be in the clear - 
you seem to be asserting that there would be some significant impairment 
to some kind of communication if it were to be forward-securely 
encrypted as I've described in other emails. maybe someone could offer 
some examples of the impairment that would occur? when I think about the 
things I do on the net on a day-to-day basis - the applications I use, 
the hosts I log in to, the websites I visit, etc. - I can't personally 
come up with an example of an application that works _worse_ since it 
switched from in-the-clear to TLS.
