	for systems that share fate on other planes, this seems to be ok. (there is a shared
	TSIG key for all root-ops, because the systems share fate on other dimensions).  Jakob
	suggests that using the same keystore is a shared fate vector.  If that is the only one,
	then I'd look at the cost/benefit tradeoff much more closely.
