Your telco knows who you are, where you live and even your credit card number or bank account. It's their business to provide you physical access from a real location and identify you as a customer by sending you invoices and receiving money from you. This means that Orange OpenIDs are verified IDs of real people as a matter of principle.
France Telecom Supports OpenID!
France Telecom is the parent company of Orange. Apparently all 40 million France Telecom subscribers now have an OpenID.
I had a call on my mobile earlier today from a lady claiming to be from Orange (my phone service provider) who told me that my contract was about to expire. She asked me for my password.
