I've never been to fond of OpenID, that's no secret. It just doesn't feel secure enough, and having to copy and paste the URL into a log-in box feels cumbersome and to the average computer user I think it could actually be confusing which is what will stop OpenID from becoming mainstream. By the way, by "average computer user" I mostly mean those that really don't use computers much and probably understand the internet as being that blue "e".

ID Selector seems a possible solution to the problem of getting it mainstream by trying to make it easier and more understandable.

• Helps new users get and remember their OpenID.
• "One click" login experience for return users.
• Consistent login experience across OpenID enabled websites.
• Takes minutes to add to your OpenID enabled website.
• Attaches to your existing form.
• No changes to your form processing code required.
• Capability aware to help users choose an OpenID provider that will just work.
• You choose which providers appear in your selector, and in what order.

At this point not sure how accessible the option is, it's something I'll have to report back on soon.
