Hmmm - suppose I download a game which takes an hour (or a day) to play, 
and want to see the result. Will the ISP keep the 5-tuple NAT active?

Of course throwaway dongles, unsecured WIFI, free public wifi, TOR, and 
so on need no mention here. But I wonder if Her Majesty knows about them?

Does anyone know the history of how and why telephone logs became fair 
game for Plod?

I mean. it's not obvious that Plod should have pretty much unrestricted 
access to comms data logs anyway.

Even then there is a big difference between telephone logs and internet 
logs, which are much more revealing.
