	I understand the "many eyes" theory, but the problem is that with 
two million lines of code, it's impossible to mathematically prove 
the code secure, and just because you have a lot of people *looking* 
at the code, doesn't mean that you have a lot of people that are 
*telling* you about the security holes that they're finding.

	Moreover, sticking with the old code prevents you from making use 
of the new "programming by contract" security features of BINDv9, 
where now each routine and function call applies near-paranoid levels 
of checking to all of its inputs, to do everything possible to ensure 
that a security compromise simply cannot occur.

	And there are many professionals making BINDv9 work in an open, 
sharing environment.  All the code is there to see, and if anyone 
wants to suggest any new code to add any new functionality, they're 
more than welcome to submit that -- just like they always could.

	The primary difference is that any code submitted would be used 
for inspiration for a redesign from the BINDv9 programming team, much 
as frequently happens with many other open source projects (Eric 
Allman always said that his biggest mistake in sendmail was simply 
taking code contributed by others, instead of taking that as a 
starting point for code he wrote himself).

	That's a very good point.  Myself, I'd like to see it being used 
by all or many of the root nameservers.  When it can be trusted to do 
that, it'll probably be good enough for me to run in production
