My guess is that my audience doesn't know the difference between a hub and a
switch. Is capturing packets going to impress them? Maybe if it were
capturing passwords??? Like the dsniff tools just catching passwords. This
isn't an in office demonstration, so I shouldn't need any waivers, but
thanks for the legal advice.

These are the numbers I am trying to impress - the threat already sits at a
