Love this! Fancy waving to someone (loved or unknown) in New York? Hold up a whiteboard with a question? Right now you can do thanks to a "tunnel" between NY and London. Seemingly it's a version of web-conferencing minus the sound but what fun. Must be loads of great uses for it - family reunions, proclamations of love, etc. What two venues should be next?
