This snippet is an improved version of the [ifusergroup](http://djangosnippets.org/snippets/1576/) tag that allows spaces in any of the group names. It also fixes a small bug where if a group didn't exist none of the subsequent groups would be checked.
At the [Internet Identity Workshop](http://iiw.idcommons.net/Iiw8) in May, 2009, I spoke to Alan Karp and Tyler Close of HP Labs about their research on authorization without identity. Here are my [Delicious links](http://delicious.com/sbwms/ZBAC) on the subject. This led me to write code to generate a "web-key," the shared secret needed to implement the access control method discussed. In his paper, Tyler Close recommends 70 bits for the shared secret, encoded as a 13-character Base32 string. I used 72 bits, so the secret is a 12-character, URL-safe Base64 string without padding characters. I'm new to Python and Django, so I welcome refinements!
