For those who haven't been following the process, the HTTPBis working group adopted SPDY v2 as the starting point for HTTP 2.0, and the first workgroup draft of the HTTP 2.0 proposal is expected to be delivered ~this month! If you're curious, definitely check out the working group mailing list.
Last but not least, yep.. I've kicked off a project with O'Reilly for a book on "Browser Networking" - really excited about it! Lots of work ahead, but I'm having a lot of fun working on it.
