the attack on the existing SKS keyservers show that we need a software
improvement. (I haven't looked at the existing solution, so I don't know if a
fresh implementation is an advantage or not.)

There is probably some extra work involved to make it a more general solution,
but it maybe even good for the company you are working for in the mid term.
(Better tested software, more ideas, more compatibility and maybe even shared
maintenance costs in the long term.)

To me it is useful to think about what happens if there is illegal contents
in the user ids, which includes personal data without permission. This could
also happen in-house, so the ability to somehow "filter" this maybe even

In my understanding it is fine to discuss this on the list. If the volume of
messages becomes too large, a different channel can be used. E.g.
wiki.gnupg.org could be used to write down arguments and research results.
Personally would be interested but I may not have much time to particiate
much. You know it is summer holiday period here in Germany.
My main point is that it is possible to do.

Probably not, because somebody else may just create a key with a user id that
contains personal data of a different person.

I don't know. It does not seems to be forseen in RFC4880 and other common
OpenPGP implementations. And with lots of stable GnuPG revisions out there in
production and OpenPGP implementations for interoperability, it does not seem
to be a short term solution.

I agree that is is nice to have second system, if just to provide history data
and revocation or rollout information if an email provider completely drops
On the gmail case I can only suggest to use an email provider that is more
privacy aware and supports WKD. (>;)) No seriously gmail my offer WKD some
day, if this is the standard emails users demand.

But why not WKD? Do you require to transport a group of pubkeys?
Then I'd suggest a https file.
