I've been playing around with OpenID on the few occasions I've had internet access over the Christmas break and have it set up, but not ideally. Currently, everything points to http://www.symphonious.net/id/ as the OpenID URL, but server and delegate. Ideally I'd like my identity URL to be just http://www.symphonious.net/ and the server ad http://www.symphonious.net/id/ but I'm not familiar enough with the whole process to make it work.
Mostly I've followed Sam Ruby's instructions, but the process was done in a few different sessions following a few other explanations of OpenID, but I think it matches what Sam describes.
Given that there's not really anything out there that accepts OpenID that I want to use, it's not really that beneficial so I'm not sure how much more effort I'll put into it. Anyway, we'll see if I ever get a chance to use it – perhaps I'll have to go comment on Sam's blog just to test it out.
