If we are going to wait to distribute the key only after the detached
signatures are available for inclusion with the key... yes..i think
holding off on the distribution should in fact only be done if we can
make use of those signatures client side. if we cant.. there's no
point in holding off on distribution. You as an individual are free to
hold off on making use of that key until there are a reasonable number
of signatures associated with the key as it sits on a public
keyserver.

How many of those people went ahead and signed the previous key as
seen on pgp.mit.edu? Which ones of those people are the people you
think have physical access to the key as Red Hat employees? All of
them? None of them? particular people on that list of signatories? But
since you can't reasonably verify that the physically had access to
the key.. you still have to trust those individuals that they did.  If
you want specific individuals that you trust to sign the key... lobby
those individuals to sign the key.

At no point have a said that out of band verification doesn't have
value. I am saying that delaying the distribution of the key makes no
sense if we must rely on the vast majority of users to use out of band
verification. If you personally need to wait for out of band
verification.. then wait.. don't use the key until you feel
comfortable with its validity. If that comfort level never comes for
you personally, then so be it.  But we aren't going to be flying
Release Engineering members all over the world with cdroms in hand to
build the web of trust. Well not unless you want to pay for the
tickets and their perdiems.

pgp.mit.edu exists... use it for the out-of-band data all you want. It
doesn't really matter whether or not I need that data to exist. What
matters is that can we realisticly build a viable web of trust around
the key, If you think we can, then go ahead...do it. But if you plan
involves flying release engineering people to your doorstep.. I'll
make sure I get your the correct addresses to send the plane tickets
and the perdiem expense money.

You'll note that security@xxxxxxxxxx already signed the previous key
as it sits on pgp.mit.edu. Is that entities signature enough for you
personally? Then wait for that signature to show up on pgp.mit.edu for
the new key after the new key shows up there.
Just as Jesse could sign it and place that signature at pgp.mit.edu
for you to verify.
Is Jesse's personal signature enough for you? is it enough for
everyone else who wants to see detached signatures? If you remember
the started with a discussion about having livna sign the key...not
Fedora release engineering.  Why exactly can't you and others wait for
which ever signatures you trust to show up on the key as it sits on
pgp.mit.edu before you make use of the key?
