A couple of people have asked me this very question as they live too far away from London to be there in person. The sessions are not yet streamed though the community leaders have thoughfully recorded every session and published them to Vimeo - click here to access all of the recorded sessions - look again in a couple of days to see tonights sessions.
No sessions from last nights talk unfortunately. Our fantastic videographer is away and we only had one speaker as our first up didn't make it in time. Although we had a great Q&A in the beginning and a Silverlight demo.
