Yes, that is a start. As long as you are comparing the "perceived" 
addresses (which I know you would be, I'm just clarifying for others who 
are reading this thread), that will work, because it won't matter what 
private addresses the remote peers may be using behind their NATs.

It will still break in bizarre routing scenarios, but people who build 
those networks are used to dealing with stuff like that.

Agreed.
