It's not the first time I've come across this, but I just got OpenDNS's hard sell on the matter in my Inbox today.  I'm not one of their customers any more, so I couldn't help find the promise a touch amusing - I run my own server, so I'm already at the promised land.

I just want to ask one question and then I'll go away to reading the archives and letting you guys go on going on.

Was the subject of a client selection of closest server option ever brought up?  It seems to me that, in parity with the DNS in general, the only congenial solution is one which does not return partial results and thus ruin DNS consistency for existing resource types.  I would be less objectionable about an option which, for instance, told me about the geographic locations of each of the available servers so I, or my OS client software, could choose.  I also want to remind web content providers that this is easy to do with HTTP redirects as DNS, and I completely understand the merit of getting rid of the existing CDN poison techniques currently in use.

Cheers,
