So, while screwing around with Twitterfeed, and grousing about having to sign-in to a totally unrelated website to use the OpenID login system, I found this:

phpMyID

phpMyID lets you create your own single-user OpenID server on your own webserver. It even includes an htaccess file for creating the correct headers if your host runs PHP as cgi (like Dreamhost does).

Coolness. I now have two custom OpenIDs: id.mivox.com and id.fckingcnts.com.

If you can install and configure simple PHP scripts, and you can generate an MD5 hash to authenticate your login, it takes about 5 minutes to set up.
