	It doesn't do round-robin, or any of the other things that normal 
authoritative-only servers should do, but which are not strictly 
required for use on serving TLD data.

	Right.  It's designed for root servers and TLD servers.  It's not 
designed for general-purpose authoritative-only purposes.

	Even for root and TLD servers, there are internal issues with the 
code that prevent it being used for some TLD providers, primarily 
having to do with the day the program wants to load all data in 
memory (and the particular type of uncompressed jump table that is 
built), etc....


	That is unless you folks have changed a lot more since I last 
looked at the program than I had thought.
