OK, thanks again, Brooks (and Chris). And I understand why perhaps it isn't wise to discuss in too great details on a public forum. I'll just ask that you folks think about the added utility of UID/IP addresses, given that a determined fraudster can delete the first and proxy the 2nd. And with respect to IP addresses, I think this is one that remains in the 'to be decided' pile of the DNT definition .....
