Everything that Kevin just said. With so much collective technical experience and intelligence available, we can work out the minor kinks in a solved problem (one-to-many audio and slide sharing). Getting the word out is also a solved problem. Both are very high-leverage -- and very good for the project. If we think about live BSDCan streaming as a fun project with classic hack value, instead of "an amorphous cloud of undoability", things will just come together naturally. The next action I see is calling for boots-on-the-ground volunteers to coordinate the local setup, and maybe a wiki page to capture the state of the project. Royce
