Technically this example does the same as
http://trac.sandbox.lt/auth/wiki/AuthFormMiddleware. Instead of
writing your plugin you would need to write isauthenticated function
that looks almost the same as identify function here. The differences
are:
1. AuthFormMiddleware does not have rememberer. Instead of that you
should use environ['beaker.session'].
2. Different return format. Most probably because of different
approach to identity.
What I like about your example is nice code reuse. However I doubt
that you will ever need to rewrite other functions from
RedirectingFormPlugin
