Site Failover

I am just putting pencil to paper for the first time on planning a
remote failover site for our co-lo production facility. As I just took
over authoritative DNS and setup of a master and slave, I am wondering
what would be the preferred configuration for another site with
equivalent services to tide us over in the case of tornado or
significant natural or unnatural disaster.
 
At first I thought two more slaves back to master to keep everything up
to date, but I do not know the impact of repeated slaving errors on
performance once the current master falls of the face of the earth. Do I
assume the manual task of switching one of the slaves to a temporary
master in the event of failover. I realize they (all four) would have to
be at the registrar as NS.
 
If any of you fine hostmasters have any schematics for this or
approached this matter with any other designs, I would love to go over
it.
 
TIA
