Add "All or Registered" radio option on the front end

HI,

Simple and useful plugin! Thanks.

I wonder if there is a php code or any code to add the radio option where you decide is the post is for all or for register users. For example a code to a into a template.php

I have a template with the editor to use on the front-end so I want add the radio option there.

Thanks Any suggestion!
