ip6tables is a doddle to use, and assuming you have a new enough kernel pretty much all you'll need will be a variation upon:

ip6tables -A FORWARD -i lo -j ACCEPT
ip6tables -A FORWARD -i $lan_if -o $upstream_if -j ACCEPT
ip6tables -A FORWRRD -i $upstream_if -o $lan_if -m state --state ESTABLISHED,RELATED -j ACCEPT
ip6tables -P FORWARD DROP
sysctl net.ipv6.conf.all.forwarding=1

(NB: you probably want more than that, but assuming your $lan_if and $upstream_if have appropriate IPv6 subnets on, and everything is routing correctly, then you get "the same behaviour you used to" when you had your IPv4 NAT... only now you have "real" end-to-end connectivity)

Traders who make money through "arbitrage" need access to more than one exchange — they're making money off the price differences of securities on each. They justify this as being beneficial to the market, because they're making prices equal across the world. Guess it's just coincidence that it's beneficial to their bottom line too, eh?

It's a lot more complicated than that: GP Practices are often private partnership businesses (between a bunch of GPs) and most definitely are run "for profit" in the sense that they have to bid for work from the healthcare commissioners (mostly this used to be the PCTs, now it's mostly the regional StHAs, etc). And the NHS does farm out some work to private hospitals to meet its waiting-list targets (and also under the banner of "Choice" that the Blairite government brought in)... ...but yes: the vast, vast majority (approx £1000/bed/day that it costs to run a hospital) is state-owned, state-run, taxpayer-funded.

About that £3500 PC...

The media reporting this story appear to be doing a good job of ignoring what that £3500 PC actually is: three years of PC, with software licensing, hardware replacement, upgrades, maintenance and support. It's not just the bare metal put on someone's desk but the full service behind it.

If you take the IT budget for a large healthcare public sector organisation and divide it by the number of desktop PCs they support, it'll probably come out at around £1000/year.

"Best efforts" might mean "best effort getting that traffic through our really congested upstream transit provider".

Something with higher quality might be a direct private peering.

Of course, it's not unknown that ISPs engineer congestion on those upstreams to force a private peering -- and you can bet your bottom dollar it won't be a "settlement free" peering.

This is what the drive to the lowest price possible gets you: a broadband that loses the ISP money in an attempt to get that TV and billboard price-point of £5.99 per month. How does the ISP make money and remain competitive? Answer: more bites at the cherry! Phorm, getting content providers to pay... etc...
