Automatically create user domains for certain roles

I love this module and use it frequently. More than once I have run into the issue where I want it to automatically create new domains for new users, except that I only want it for select user roles. Meaning, a user with a role of 'affiliate' should get a new domain created while a user with a role of 'member' should not. I use content profile and auto assign role modules to get different roles automatically assigned on user registration, so this could still get fired off immediately if the settings allowed you to choose roles to apply the automatic domain creation to. What do you think?
