Speaking of which - I was wondering about this when I saw the lecture
announcement (couldn't make it - it was too short a notice for me to
catch a flight from home :) and would be curios of the presenter or
attendees know the answers:

1. What sort of barriers were tested?
2. Are there any practical counter-measures that can/should be employed?

Cheers,
