I use google app engine a lot, and would love to have mention in the main content of the book when features won't work on GAE. some are now, and others are only in the GAE section at the end.
also not everything in http://groups.google.com/group/web2py/browse_thread/thread/cd89f11de4d23b53/f67faac66a695ca2?lnk=gst&q=google+app+engine+production#f67faac66a695ca2 has made it to the code, so those tips would be nice in the book (especially the caching of wsgihandler.py - it saves 90% of the execution time for a simple page). http://www.web2py.com/AlterEgo/default/show/248 would be great in the book as well. thanks! cfh
