		<description>[...] Pero los que más me han llamado la atención son acerca de utilizar varias direcciones OpenID por usuario en una misma web. En junio, Simon Willison comentó en una conferencia que es posible utilizar OpenID para demostrar quienes somos en otras webs. Por ejemplo, con una cuenta OpenID de AOL podemos demostrar en cualquier web quienes somos en AOL, por lo que podrían enviarnos mensajes instantáneos. Poco después Dr Nick expresa las grandes posibilidades que le ve a este sistema, que tan sólo necesita permitir que los usuarios puedan añadir múltiples direcciones OpenID a su cuenta. Aunque pueda resultar útil puntualmente, creo que es complicar la vida al usuario. Realmente si AOL permitiera utilizar el OpenID que se desee, bastaría con utilizar el mismo en ambas. Automáticamente cada web sabría que la otra cuenta le pertenece al mismo usuario. Si no, para poder hacer una integración efectiva necesitaríamos utilizar varias direcciones OpenID en cada web, con sus consiguientes autenticaciones (una contraseña por cada una, si se tratan de proveedores o cuentas distintas). Y aún no hemos tenido en cuenta las APIs. [...]</description>

		<description>@martin - yeah, that'd work for users.

It'd be nice if you could specify a list of delegates in your head section, but the "is it live?" check is a human one and not done by the consumer app, so I guess that won't work.

So, changing your openid delegate is a manual task for each user. I guess that's annoying.</description>

		<description>I like Squeegy’s comment, emailing a one use login link with a short expiry time is a good alternative that keeps things reasonably simple. But overall, supporting multiple OpenID’s is a positive thing and the email login should only be used if supporting multiple id’s would be too difficult.

Or.. support both!</description>

		<description>If the OpenID service is down why not revert back to the standard web app login? Allow the user to retrieve their password (and possibly username) based on their current OpenID. 

The added benefit to this approach is that the user is still using the same identify on the system and not another OpenID.</description>

		<description>@brian - from my understanding, is the same problem that users might have if the actual site itself was spoofed. E.g. if you logged into ebay directly at a spoof site.

I didn't read the details of the openid server spoofing - I'm not sure how/why the user was redirected to a phony login portal.</description>
