	If you can do rsync, then just set them both up as masters, and 
rsync over the named.conf and the associated data files.  No need to 
have one set up as a master and the other as a secondary.

	This technique also has the advantage that if there is an 
extended outage, both systems will continue operating completely 
normally, and there is no risk of the secondary deciding that the 
data it pulled is too old to continue being served.
