Part of the day at Google I/O BootCamp was a BarCamp. And, I did propose a session. After spending a year working with GWT on a LAMP Stack without an application server, I felt that I had a lot to share.
If I had gotten 1 more vote in the end, my session would have happened. Just proposing the session got some great conversations going about GWT on LAMP. I am learning so much here.
