snape -- BBB Firewall is a KUAL addon that should block connections to Amazon's servers. AFAIK it should work on the K4NT, and it is a Kindle-side alternative to setting the block in the router.
Then you can take it traveling, and if the WiFi turns on (whyever it does, of course) -- it still cannot connect to Amazon and return your books.
