Yes, exactly. The UID just says "Anonymous" or whatever you want it to say.

Yes. Either the user needs to be this savvy, or his tools (MUA, or GnuPG)
needs to recognise the special form e-mail address and do this.
To automate it, either the MUA or GnuPG needs to recognise the special form
e-mail address, but no other changes are necessary (f.e. the keyserver can
stay the same).
By the way, the way I see it, the e-mail address really exists. You can mail
to dkg--noenum-0EE5BE979282D80B9F7540F1CCD2ED94D21739E9 at fifthhorseman.net
and it arrives. Demanding the MUA to automatically strip it and mail
dkg at fifthhorseman.net instead really hinders adoption.
I assumed Hauke Laging's high-entropy e-mail address variant also needed the
e-mail address to actually exist, otherwise I don't see how that variation
could meet the requirements, namely that possession of the e-mail
address is enough to get someones public key.
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
My key is available at http://wwwhome.cs.utwente.nl/~lebbing/pubkey.txt
