Thanks for the ideas.
I was inclined to use the -s option but realized that the keys has to be
distributed and maintained on controller host (the host from where we
execute the rndc) causing security issues. Also we have to maintain a 1-1
mapping of DNSservers vs keys if each DNSserver has uses different rndc key.
Suggestions to use pdsh or other shells looks interesting but current
environment restrictions is forcing me to think me about a script based
