..setup your slaves to ping|pong|poll or nsupdate etc the master and
take over when it fails.  Obivously you want only one master at any
time, and you'll want your dead master wake up as a slave or go 
growl  "Ok, I'll take it from here, step down, slave!"

..disclaimer; I don't play with name servers yet.
