I'm not sure if anyone else is interested, but I think this would be a REALLY good add-on for our sites. It would enable us to allow our users to shop on our site without having to set up a new account.
 
I think this would be very attractive to our userbase and would like to know if anyone would be willing to pitch in on it?

 
I am implementing Windows Live ID custom using SSO in PHP. I find no sample code for PHP code using SSO. I find some sample for PHP but it is not for SSO. SO Please can u give me sample code using SSO in PHP.
 
 
Thanks in Advance,

I'm interested in this if you can point out exactly what the benefits you see would be.

This page describes roughly how to do it and has the links to the relevant download pages. There is a php download.

Seems to be straightforward enough. Might be of limited benefit to shoppers by providing their details for shipment etc.
