No, I wasn't really proposing that the "special zone" contain literally 
TXT records that form an include file, just that it contain enough 
information so that the appropriate zone definitions will be 
automatically created, whether those definitions take the form of a BIND 
named.conf include file, registry entries, database entries, or 
whatever. For that matter, if you were willing to maintain such a thing, 
you could have different "views" of that special zone, so that you could 
serve up different data to BIND servers, MS-DNS servers, or whatever, 
and they could use that data to build their zone definitions.

The "delegation override" mini-FAQ is mostly BIND-centric, I admit, but 
not completely so, since even Microsoft DNS supports stub zones these
