And this article at Google (expand the first [+] area) suggests you can use non-www domains just fine:http://www.google.com/support/a/bin/answer.py?hl=en&answ...Where did you get the idea you couldn't?(The only trick might be something specific to App Engine for generating the www -> non-www redirects, as you won't have the usual access to web server configuration options. But that'd be a better question for the App Engine forums.)
