Could we please organise to sign each other's PGP key.
To prepare, all that we each need to do is to print scraps
of paper with our own Key ID and Fingerprint to give to
each other.
After the event, we do the actual signing back at our offices.
I have recently created a new stronger 4096 key by following:

Some useful notes about key signing are at:

... but really all that we each need on the day is
to be able to exchange Fingerprints.
