InfoPath posting anonymously

This theme seems to come up a lot. I did some cursory searching based on a user's request
to allow anonymous users to post to a document library.

This solution is a more classic approach using the code behind in VSTA.  This allows us to encapsulate the request with a service account to make the submission for the anonymous user.

   This solution relies on InfoPath 2010 tight integration and expanded capabilities of SP 2010 Enterprise.
