'not at all' wasn't the answer i was thinking on. Yes, RIPA is an act  
of parliament, a statute - law. But a contract is also covered by law  
too. Whilst statute out-ranks tort, there's nothing stopping them from  
interacting. I would therefore have a strong suspicion that the t&cs  
for your connection with your isp will certainly contain clauses which  
discuss handing over logs etc to law enforcement on request, but i'd  
also suspect that there would be sufficiently vague language which  
would permit the kind of behaviour that has been discussed. This may  
be in the form of disclaiming who owns the clickstream data (as the  
creator of the system, do you own it? or does the facilitator who  
records it?) or perhaps there may be clauses for aggregate data being  
used for quality testing and user feedback (a great way to say  
'advertising' btw).

my point is, whilst ripa protects the overt behavior of otherwise  
covert surveillance and interception, i don't believe it necessarily  
governs any or all commercial activities that an isp may partake in  
which other parts of law may provide cover for. Remember, your first  
legal point of call with your isp are your t&cs, not some pre-agreed  
statutes - i would consider ripa to be somewhat perpendicular to that.
