My take is, if you don't actually use the OpenID URL, it doesn't really exist. The same way a Wiki page doesn't exist until you edit it.Well, until you create a link to a Wiki page and then edit it, it actually does not exist, i.e. it's not addressable. My AOL OpenID manifestly does exist and is addressable. What's more, anybody who knows (or can guess) my AIM screenname, can get to it.
John goes on
Another important point is that you can point at the AOL OpenID service from any web page you own in order to turn its URL into an OpenID. The minimal requirements are basically that you have some AOL or AIM account, and that you add a couple of links to your document's HEAD:
Of course, I don't want to use OpenID's delegation mechanism to point at this AOL OpenID - I don't even want the thing, why would I direct RPs to it?
If anything I'd want to instead edit the AOL HTML page to point at my chosen OpenID provider and URI. John suggests that this is now possible
We added this to our blogs product in a few minutes minutes (sic) and it's in beta now.I created a blog at AOL in order to try it out (NBARM - Nothing But a Redirect Mechanism) but I can see no ability to directly edit the HTML header to add the OpenID delegation tags.
Does John mean that AOL supports OpenID as the delegatee, but not the delagator? A business model peaks through the clouds.
