Thought this might be relevant to your guys' interests -- the SIAI's annual Singularity Summit is this August in San Francisco. It looks like it's going to be a pretty interesting event; speakers this year include Ray Kurzweil, James Randi, Gregory Stock, and a lot of scientists and industrialists who are pushing the edge of the technology curve in interesting ways.
