thanks steinar for your support, ISC people seems to busy with 
explaining syntax errors in named.conf then to comment a single word on 
the subj :-(,

I am wondering what CNS people says about bind9 recursive capabilities, 
it would be interesting to meet them, since they definitely know both, 
and they have already done their homework:-)
