[cabfpub] Pre-Ballot - Short-Life Certificates

Maybe we should consider shortening the validity period of OCSP responses -
that would narrow down the window of vulnerability and even up the playing
field.

There are so many shaky arguments in this thread it's impossible to apply
any sort of logic about My assertions vs. Yours.  Someone needs to collect
up all the he said/she said statements and apply some probabilities and
logic to this if it's to be of any use at all.

If we're going to create a new type of certificate which is exempt from
revocation checking we need to tag them as special - a new extension or
something so that they can be processed differently.  Merely relying on the
short validity period or the omission of the AIA does not adequately convey
the special rules which browsers may apply when validating it.  There should
be something explicit.  If it's critical, then the AIA can be omitted, if
it's not critical then the AIA needs to be there for anyone other than
Firefox that comes along and tries to validate it.
