Now a company called NetPay.TV - I have no idea about them, really - have started a service that sends out a 6 digit pin over the SMS messaging features of the GSM network for the user to type in to the website [4].
Authentify (http://www.authentify.com), does the same kind of thing. They put a number on a web page, and then they call you and you key in the number. They were founded in 1999; not sure if they're still active.
