This is not part of the session problem then. If you have a specific OpenID linked to a specific IDP. If the IDP becomes unavailable, you will need to find ways to deal with it, perhaps allow the user to link their existing account to a new IDP. That's a good problem that I think we'll have to deal with. I listened to a presentation on password recovery process and it's no joke the amount of effort that they had to go through to make sure it's i) easy enough for dumb users, ii) secure enough from the malicious, and iii) complies with their legal requirements.
On the long term cookie issue, we still have the usability problem of requiring the user to allow validation forever as opposed to a single use basis. I'm thinking it would be useful to have finer level of granularity, ie. validation for 10 min or 10 hours. The IDP can return an encrypted token to contain that information which will be part of the session cookie that would need to be passed subsequently.
