UK ISPs Consider VPN To Avoid Piracy Crackdown

Mark.JUK writes "Broadband internet providers in the UK are considering whether or not to follow the example of a Swedish ISP, Bahnhof, which recently put all of its customers behind a secure Virtual Private Network (VPN) in order to circumvent new European Data Retention and Internet Copyright Infringement laws. By doing this, it makes their logs less useful to outside forces (e.g. rights holders) and allows customers to use the internet anonymously. However, several UK ISPs, including business provider AAISP (Andrews and Arnold), have suggested that there may be better solutions than sticking everybody behind a costly VPN. AAISP's boss, Adrian Kennard, claims, 'something ISPs will be doing anyway, carrier grade NAT, will create a similar anonymity as there is no requirement to log NAT sessions.' Meanwhile, Timico's CTO, Trefor Davies, warns, 'It would be a pretty costly project for all ISPs to implement such a system. It would also bring with it risks – suddenly it becomes a lot easier for governments to start monitoring all your traffic because it all goes through a single point (or at least a few points) on the network.'"

Any side effects of NAT?

I'm not all that familiar with the nitty gritty details of NAT.
Would a site like /. rate limit posts coming from multiple users behind a NAT?

IIRC, one spammer behind a NAT can get everyone else blacklisted.
Talk about havoc for that ISP's customers.

A VPN sounds like the smarter of the two ideas.
