You could rig up an NS with a copy of "local zone". That NS will not forward 
any queries for that zone since it is authoritative for "local zone". All 
local clients query that NS. It will forward queries for any other zone, when 
you guys are online. The only issue is to keep your "official" outside 
zonefile in sync with your internal file. HTH.
