[iot-wg] co-chair selection procedure

We still have to sort out an appointment procedure and that's my fault. Sorry. It was too easy to procrastinate when $dayjob got in the way.

Anyways, we need to get something sorted soon. Ideally, I'd like to get WG agreement by mid-September (allowing for the summer holidays). That would allow us to run the appointment process and have a stuckee in place before RIPE77 (Oct 15-20th). If you have concerns that more time is needed for either agreeing a procedure or then using it, please speak up.

I would also ask the WG to avoid the temptation to rat-hole or over-think the selection procedure, for instance by proposing elaborate steps to apply in corner cases that in all probability will never arise. We're just appointing a WG co-chair, not the Internet's Supreme-Leader-for-Life. We can always change the suggested process later if practical experience proves it is broken or needs improvement. I hope we can just put something quick and simple in place that solves the immediate need.

Note too that there is no mention of elections or votes. This is deliberate.

Can we live with the following?

(1) The IoT WG will have 2 co-chairs who serve staggered 2-year terms.
(2) A co-chair cannot serve more than 3 consecutive terms.
(3) Each year, the longest serving co-chair will stand down and subject to (2) may make themselves available for re-appointment.
(4) The incoming co-chair will be chosen by the WG using consensus and the remaining co-chair will make the consensus determination.
(5) Any circumstances not covered by the above will be resolved by the RIPE Chair whose  decision will be final.
