Testing this would essentially do

    dig example.com ns
    <grab the list of dns servers>
    dig @ns1 example.com soa
    dig @ns2 example.com soa
    <compare soa records to see if they are identical>

Xymon can do the DNS lookups, all that is needed is to cook up the 
necessary data analysis.

I think this should be a separate test from the normal "dns" column?
