"Expecting everyone to make a big modification like installing a Java-based browser to their infrastructure is crazy." I agree. Google is (IMHO) doing this because they view GWT as the near-term future of web development and it seems likely this will be baked into the framework sometime soon (see http://code.google.com/p/google-web-toolkit/source/browse/branches/crawlability/ http://code.google.com/p/google-web-toolkit/source/browse/br...). Katharina Probst and Bruce Johnson are both GWT team members, and as far as I can tell Dr. Probst is leading the engineering effort on the GWT side to support this. It seems to me that if you're not using GWT, this will be far too much effort for you to implement.
