A copyright notice does not prevent anyone from accessing or using the data on a website.

Also remember that copyright is a matter for a civil court so you'll not get a definitive answer to thse questions until and unless a possible breach occurs and you bring a case against those responsible.

Also remember that you have to prove that your copyright has been breached and then establish who is responsible for the breach and in this case it may be the end user especially as BT have a clause that makes the customer responsible - it's the reason why they can restrict your account if anyone in your house illegally downloads copyrighted music.

The copyright issue can only be settled in court after the system goes live - until then it is a moot point.
