Wholeheared agreement (who'd have thought I'd ever be wholeheartedly
agreeing with Branden eh?)

It does matter.  You have to be certain.  A person I know well enough
that I would recognize their voice, have seen their ID, and calling me to
verify keyid, size, and fingerprint is good enough for me (because I have
good memory for what people who are ... um, unique and stand out in my
mind (krooger for his trademark silly hat among other things) is enough
for me if I can be certain it's them, but otherwise, I need to have met
them and be sure.

Another reasonable way to identify someone who wants a new key or userid
on their old key signed is if they send me a message signed by their
current key (which has my signature) with the new one and a request.. 
This is good if you've got an old email address that is no longer valid
(my earthlink address) and you'd like it removed.  Note this is not easy
to do with PGP at the moment.

You're right.  In fact in most states it's ILLEGAL to do things like scan
ID for the purposes of verification of identity.  I mentioned this to
james when we talked---Oregon was such a state.  You can however get ID
which lists an alias.  I mentioned to Social Security the lasttime I was
in there for something or other (notifying them that I moved IIRC) and
they said that if I wanted to wait they'd give me a card with "Joseph
Carter" on it as opposed to "Thomas J. Carter" since I don't use my first
name.  I could have done the same for DMV ID, but again chose not to.

No, you're right.  Identity fraud will get you time in federal prison. 
You can get any name you want on your ID, as long as their records can
reference your legal name with it.  And you can change that for a
processing fee.  Of course it will still list your given name prior to
that.  You cannot escape Big Brother!
