Will more Websites offer SMS password recovery?

Gmail now allows you to recover your password by SMS

In what is a very obvious “head smacking” move Google has allowed users to fast track access to their accounts by a simple SMS recovery feature.  The existing process of having to contact Gmail support is time consuming so anything to speed up the process of reclaiming access to your account is a great move forward.

This SMS feature may not get around the fact that people can guess your simple passwords, what is the answer to your secret question or your partner/mates can’t steal your mobile.  It is a great move forward and could prove quite useful for AdWords/Analytics accounts as web developers often move on leaving companies without access to their accounts.

This would be a great feature for OpenID accounts and even Facebook with the rise in accounts being hacked.  Google has made an interesting move forward but how does this integrate with Google Voice or Skype?
