[fw-auth] Feedback on Zend_Auth_Adapter_Flexible?

Hello!

Several months ago I posted a proposal (http://framework.zend.com/wiki/display/ZFPROP/Zend_Auth_Adapter_Flexible+-+Adam+Jensen) for a new kind of authentication adapter which simplifies the process of allowing multiple modes of authentication (e.g., email/pass and OpenID) via the same controller and view code. 

Unfortunately, I haven't received any community feedback, which either means my proposal is (a) perfect, or (b) totally uninteresting :)  I was hoping I could entice some of you to take a look at it in the next couple of days to see if there's anything I can improve before I promote it to Ready for Recommendation.  Please let me know what you think; personally, I've found that this approach saves me a heck of a lot of code, and I'd love to see it added to the framework.

Thanks!
Adam
