That is an interesting point. I think the perception by some is that we would like to have 'seamless' use of openid/oauth between various grids as folks might move from grid to grid using OGP, MXP, HG or other interop notions. So, popping up a password dialog in the midst of a teleport might be 'off putting'.
I had heard there was a use case where that was not the case, but admit that I am not all that familiar with the inner workings of openid/oauth. If we need to have a password dialog in interop teleports, well, that may be a small price to pay.

It's a good tech, and the community has done a lot of work getting the open model recognised. You'd be looking at at least two specs, openid and oauth to start with, then there's a few others such as sreg and attributute exchange, maybe pape, so there is some complexity there. Also bear in mind that this was designed with standard pattern is username/login from the 3rd party interface, so you'd have to server up, for example a google login form (or every other kind of login form) when singing in, or perhaps when teleporting, which might not be the ideal user experience. > >> FOAF+SSL (aka Secure Web ID), is a much newer 3.0 techonology which >> has less complex interactions (no third party authentication or >> passwords required, it is a client server).

Do take a look if you get a chance, it's a good system, and SSL PKI is mature and tried and tested, it is used to log in to secure email, VPN, ssh and many other systems. You just need to store a public key with the users assets and you're well on your way.
