You can specify multiple forwarders if you have more than one server 
already set up the way you want.  Named will find one that works and 
cache the results locally for its time to live.  Once you have a couple 
of robust boxes configured it is easier to do that on the rest than to 
deal with local zones everywhere.

Or, if you really want to act as a secondary, just make a zone type of 
'slave' and specify the masters and a file to hold the zone info.  You 
will also have to permit the transfer to this host on the windows server
