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.
Thanks,
Mark
