I just finished addressing a meeting in Islamabad, Pakistan -- Synthetic Biology and its Dual Use. I was scheduled to give my talk via two-way video teleconference that turned out to be ... one-way. So rather than being able to interact with my audience, I had to simply page through my presentation on my end and hope they were still listening. I was basically practicing my talk, except there was a live video connection to the other side of the world. Very strange.
