This stuff about customers and things sounds too hard.

Steve, have you actually had to do anycast without having control of  
the routing hop in front of your service providing hosts, or is this  
getting unnecessarily complicated? I'd imagine that the ability to  
install routing equipment would be a pre-requisite for any anycast  
service deployment..

Perhaps what would make more sense here is Foundry (F5, etc.) building  
an anycast feature - anycast prefixes are withdrawn when a cluster  
relying on that anycast prefix goes below a threshold. These load  
balancing switches already do all this service health check stuff and  
have done for years, so why are we re-inventing the wheel?

ps. I'm amused that your message that started with "i think the  
minutia is good, especially after a long weekend of layer 9 threads."  
ended with a paragraph of L9 :-)
