A more useful option would be if someone wrote a simple utility which 
would calculate and add the TXT records to the DNS. This could be run 
once, then immediately the administrator could manually remove any 
for entries that are to remain 'safe' from DHCP updates - thus 
keeping important records safe.

A generic script which automatically deleted records would be rather 
dangerous unless it had access to an exception list.
