I'd be interested to know how much node-flapping goes on. If you :-

$ dig +short @ chaos txt hostname.bind

you will get the unique ID for the node you are hitting - I'd be 
interested if this changes much for your location.

Our tests show that it doesn't change that much, except (for example) 
during maintenance
