Chrysalis,
With all due respect,
the documentation is there for you to peruse at your leisure and you will find the answer to your "questions" - not that the answers to many are not already provided within the thread if you'd bother to read the posts in their entirety.
Your
"I am not concerned about isp's t&c's" shows that you have little or no understanding whatsoever of the situation and that you are not reading, or you are failing to understand, replies offered to you.
I am not prepared to put things in black and white for you only for you to pretend you can only see grey.
Good luck to you in your quest.
