I think it'd be better to implement this as either a META or a LINK 
element alongside a standard protocol for communicating with the 
nominated URL.

This way the site can declare on *all pages*, rather than on the 
forms-based login page, that it accepts OpenID auth. This allows the 
user to go to the RP's home page (or any other page) and click the 
"OpenID Login" button on the browser's toolbar and have it work.
