Re: ND-proxy applicability and loop-prevention

I agree with Erik and Hesham that loop preventation
is something that we may wish to have. A couple of
comments on what Pekka wrote about detection:

This is a danger, yes.

Right. Or add an ND option to a proxied query, and detect when you
receive an option which you inserted by yourself.
