I think that this is a great idea, however, I want to stress that the appropriate forum for the discussion of _results_ as opposed to the development of the tools to gather them is NOT the IETF, but rather NANOG or IESG. Any attempt by a WG at IETF to benchmark issues related to operations, or to attempt to compare operational aspects of ISPs, is something that I will not find particularly friendly. OTOH, I *would* like to see NANOG and IESG be the place to test whatever the WG comes up with and to discuss and share results. Sean. P.S.: Yes, that's Canadian understatement at work in the second paragraph.
