As with every year I will be at Build to learn more about the Microsoft APIs and product sets.
I would like to be able to attend an (interactive) session or two on PhotoSynth 2.
Photosynth is one of the most unknown Microsoft technologies and I feel that some show and tell at an Event like this would be really good for PR and also allow the community to meet some of the Photosynth Team.
You could even talk about some of the technical and scientific challenges you have solved or about how you have leveraged WebGL.
Even if you cannot host a session, even an evening in a bar to talk about Photosynth and maybe some expert lessons would be possible.
I will keep my fingers crossed to see you in SF.
