Restricting a group of users to run only "rndc reload" and "rndc
reconfig" via sudo is trivial. sudoers(1) will explain how, and
the sudoers file that comes with sudo is chock full of examples.

Off the top of my head, you would do something like this:

    User_Alias  DNSOPS    = user1, user2, user3
    Cmnd_Alias  DNSRELOAD = /usr/sbin/rndc reload
    Cmnd_Alias  DNSRECONF = /usr/sbin/rndc reconfig

Don't know if that parses properly, but you get the idea.

As far as editing only zone files, if you know the names of the files
that they need to edit, something like this is sufficient:

    DNSOPS      ALL       = sudoedit /etc/named.conf
    DNSOPS      ALL       = sudoedit /etc/rndc.conf
    DNSOPS      ALL       = sudoedit /var/named/zone1
    DNSOPS      ALL       = sudoedit /var/named/zone2

However, if your users need to be able to create/modify/rename files
under /var/named (as you mentioned in your OP), then you will need a
properly written wrapper script.
