I'd agree that we should be clear (and explicit!) about 
con/dis-junction. However, (and this IMO is a big point) 
I don't think we're doing a general secure db lookup, I
think of this as key management, and in particular, I think
that xkms is only useful if it can sit in front of e.g. an
x.509 or pgp pki. I can't see that you could map a general
db lookup to those infrastructures in any sensible way.

Definitely one where we need concensus.

Stephen.
