but it's still the real answer.


Yes, RIPA is an act of

I hope not - they can do so under a demand under RIPA, but they can't do 
so for any other reason (barring a few other laws).

Nope. See RIPA sections 1-3.

It isn't about who owns it - it's about intercepting it.

Nope, that's simply just not how the law works. T&C's in a contract 
can't ignore statute, and they can't make something which would 
otherwise be illegal legal.



Of course I may be wrong, I am not a lawyer - Nicholas, would you care 
to comment? Simon, perhaps you could, possibly, in this case?
