Brian, I would be very happy with the language you mentioned: Solution must support {pick your favorite SNMP terminology: command generators/responders/.../agents/managers} on either side of NATs and firewalls Whether it's CH or some other Thing, as long as it's not incredibly contortive, I'm okay with it, and I'm perfectly fine with a WG evaluating such solutions and making a considered decision.
