I understand that if I have full control over my domain, I can set it up so that I can delegate the task of authenticating to another OpenID service provider.

The problem is, what I'd like to do is to get the LiveJournal server to pass the authentication to someone else, instead of having LJ doing it.

Preferably what I'd like to do is get LiveJournal, when asked by a web site, say, "No, I don't do it anymore -- go to this address". The plan was that this address would then be in a domain I fully control, which then would pass it on to whichever service provider I choose.

I don't even know if I've gotten my understanding of OpenID right, if all this shenanigans are necessary, if my question makes sense, or if it's even possible with a service provider like Livejournal.

ETA: Doing a little more reading up, and examining the source for my LiveJournal user page, I note that this particular line in the file's <header> area:

<link rel="openid.server" href="http://www.livejournal.com/openid/server.bml" />

I suspect that changing this will allow me to forward OpenID requests to whomever I wish, I think; so far so good.

Now comes the hard part -- figuring out how to change all of that using LiveJournal's customization options, if that is at all possible (here's hoping I don't need to pay to get that functionality).
