Well you can't do anything about home users. They install anything that a phishing email tells them will make their Internet faster. You might hope that the IT team at "one of the largest employee-owned engineering and related consultancy services companies in the Asia-Pacific" might have a clue though.
If those systems are getting more and more common then I'd suggest that people may like to start looking at ways to augment the GLSB that you're using.
You mean like this? http://tools.ietf.org/html/draft-vandergaast-edns-client-ip-01 At the present time GSLB is good enough, cheap and pretty much works. GSLB used by just about every CDN ( If I use google DNS Akamai happily serves me up pages from the US rather than from the local farm ) so people will find much of the Internet equally bad. But in reality the big reason I have servers in NZ is that *despite* the added cost it makes things faster for most customers (partially due to the crappy international bandwidth many ISPs have). If a small percentage of customers hack their settings and make us as slow as a random US website then it's not a HUGE thing. I guess I could GEOlookup a few 1000 HTTP requests a second [1] and redirect the idiots to www.imreallyinnewzealand.mydomain.co.nz but that would just confuse people. Sure Google do something like that but they get to spread their costs over a lot more users.

They also only do it for stuff their GGC CDN handles, which is Youtube video and other things where the URLs aren't in an address bar, like (I think) map tiles. Once you do the initial lookup you can cache it for the duration of the session, I don't imagine the load would be that much higher if done intelligently. You also only need to do it within code that generates HTML, assuming you do that dynamically[1]. You could even store it in a cookie with a lifetime of an hour or so, so you don't have to look it up if the customer thinks they already know where they are. Of course, you only have to GeoIP the stuff you consider to be NZ vs. the stuff you consider to be non-NZ - unless you have servers in other places. That's a fairly small prefix list that you have to hit once per cookie lifetime, so, it's a fair bit easier than I suspect you're imagining.
