Frizzle is still experimental/beta, but it seems to have a lot of potential for the maker/hacker community to document workshops and build sessions. Just setup a webcam, point it at the workspace, and then share it out when you're done (without plugins or desktop apps).
Frizzle was made as part of the Chaos Collective's craft night in 24 hours. All source code is online and easy to read.
