It is ironic that Eric's posting arrived while the US based Aviation Justice are
resorting to videoconferencing after their invited speakers were barred from
entering the US. I suspect that while many of the goals of conventional
conferencing can be achieved by videoconferencing there will always be some
intangibles that can't, though maybe in this case they might just be outweighed
by the effects of the publicity the ban led to.
Go to <http://www.airportwatch.org.uk

speakers into the US, as well as a link (via "More" on the relevant article) to
the Aviation Justice website with lots more about the issue.
