So this is basically a tunnel over the open internet with all tunnel endpoints in the same (or cooperating) administrative domain. In that case it's indeed up to the participants to deal with and debug. So the tunnel model I don't mind. Can we be certain it indeed fits all deployments and leaking isn't possible. Theory and practice are the same in theory, but not in practice :) Cheers, Sander
