UI patterns

[Drew McLellan]

Hello

I'm wondering if anyone's published any thoughts on patterns for user  
interface flow for sites consuming OpenID.

Thinking particularly of the more complex scenarios of retrofitting  
OpenID to existing applications. There are a few good examples of how  
this can be done (magnolia etc), and I thought it might be worth  
documenting.

Does anything like that exist already that I've not been able to find?

Thanks
