This is great stuff--the summit was packed and buzzing. Very much felt like the beginnings of something big. I spoke later in the day on the Open Hardware Business Models panel. But the business models are all pretty simple: Give away the bits, sell the atoms. Charge enough so that you can keep doing it.
This radical idea of making a profit so you can grow and keep up with demand would not be unfamiliar to the Babylonians. As my co-panelist Phil Torrone put it, "Professors keep coming out to interview us on our business model, and then they later apologetically email to say that they can't use it because it's too boring. Maybe we should have a Facebook app or something."
