I'm sure you're right, Paul, seems a shame as (right now) I can't see 
the issues, where the QNAME is constant, plus the query packet size will 
only be very slightly bigger.

Should also be better for the authority server as its gone to the 
trouble of pulling out the data for that name already, so supplying more 
than one RR would be less overhead than running the query again from 
scratch .... well it would on our system anyway!
