I have now put together some basic code which successfully interacts with OpenID servers.

Unlike other solutions it doesn’t requires any other libraries or special languages/features on the server other than CURL support (with SSL) which is fairly common.

Unfortunately during this time OpenID has upgraded to 2.0 and certain providers like Yahoo will only accept 2.0 queries and not 1.1 which is all the code can handle.

But if there is any serious interest, I could get bbPress to accept openid from wordpress.com/livejournal/aol/etc. which continue to allow 1.1
