One of the key topics we're covering at Over the Air this year is "open data": how mobile developers can take advantage of data and APIs to build great stuff. That's why we're very excited to welcome back Christopher Burman, who will be presenting on Pachube, a company that works to store, share & discover realtime sensor, energy and environment data from objects, devices & buildings around the world. Christopher's talk will be about the augmented reality stuff he's been working on at Pachube:

the 'porthole' (http://apps.pachube.com/porthole) software recently released in alpha and the challenge of creating the forthcoming mobile version. He'll also give a couple of demos of the stuff in action, talk about Pachube as a platform in more detail and explain why AR, especially mobile AR is so exciting for Pachube and why other developers should be excited too.
