Yes, you can use service builder in a hook. What you want to extend?

Can you provide me any example where service.xml has been used to extend or define/add an entity using hook?

I'm not sure if we have an example here but take a look: http://svn.liferay.com/repos/public/plugins/trunk/. The user is guest without password.
