hmm;-) ok i know that, but you assume someone how run nsd on a server
which has user how send so much fake notify to which can cause problem?
and if it's accept notify from anywhere than if the handling is buggy it
still the same problem since the remote system is also can be multiuser
what's more probably this system owner has less control/knowladge over
the other system than his own system.
