Over two days in July, we flew in members of the Wave engineering team to go deep on various aspects of federation and the APIs, and we taped all the talks so that remote developers can hear what they had to say. The slides are linked from the API media gallery and the protocol site, but we've also embedded links and a player below for you here. Enjoy!
