Solicitors.  (Declaration of interest:  I'm a solicitor.  But I don't do
conveyancing, so please don't ask.)

How will you know who they are?  The same way you do now:  look them up in
the phone directory, go to their office.  If you feel really suspicious
(hardly ever happens -- only twice I can remember after 30 years in the
law), check with the Law Society, check their practising certificate, ask
to see a passport.  While you're at it, get their public key from them in
person (forget about a licensed CA certificate).

How do solicitors know who other solicitors are?  Same methods seem to work
OK; sort of web of trust.  No doubt we'll go over to iris recognition one
spring.
