 lets see... (from previous discussions on the usefullness of tweeking
 the version)
        
        wearing my blackhat, i have to decide which system is worthty
        of my talents... which one should I pick?

        version "bad-ass-bind";         
        -or-
        version "9.1.0"

 of course I could be running 4.8.1 and simply recompile so it _reports_
 a bogus version but the profile of a 9.1.0 code base is -very- distinct
 from a 4.8.1 code base... esp on replies to queries.

 Pick your targets carefully.



Why not jus return some 'bogus' version ??? like this option allows:

version "bad-ass-bind";

While it's not exactly a problem, it does give away that you're running
bind9 (I do like the new 'version' option where you can set the
version.bind reply) even if you change the version to appear to be a bind8
server.

"allow-query" lets you control who can see that information:

zone "bind" chaos { 
        allow-query {
                127.0.0.1 ;
                xxx.xxx.xxx.xxx/len ;
        } ;
        type master; 
        file "filename"; 
};
