Rob Wilson raises the issue of ensuring that
someone undertaking PGEA via a network connection is indeed who
he/she claims to be.

There seem to me to be two classes of solution
a simple human-factors one
You bring in a trusted person, who can personally verify that
this indeed is the person it is claimed to be, to watch what is going
on, and who can testify to that effect.
an unforgeable identification
You make use of some form of unforgeable identification
(fingerprint, retinal pattern) which is embedded in the system in
such a way that only the person using the system can be checked, and
the checking process operates continuously during the testing
process.
My guess is that the first can be implemented, using negligible
amounts of technology, in a matter of a few days negotiation as to
who might be a trusted observer. The second will take several years.
A final point. If the person to whom you give a password is not to
be trusted, then you are going to have REAL difficulty in enforcing
any level of trust.
