Which is fair enough, but why not have a few providers rather than
having to implement several of them on every site? (And people having to
use them on everysite.)

Err, who? AOL, MS, MyOpenID? There are quite a few providers already!

Ok, but just remember that you should only have to do it once.

Perhaps, but if you are so inclined, you can set it up to use your own
homepage. All you provide as a login is your URL.

Yep, but it's gathering momentum pretty quickly. There are many
providers, it's the sites that need to catch up now.

Regarding using email:

Actually, it's quite easy to automate, or at least make very quick, and
can't serve as a trust mechanism. You could also automate the creation
of OpenIDs, which is why you would still need a trust mechanism.
Possibly one of the methods I suggested, although I'm sure there could
be other methods.

Kind regards,
