To add my 5 cents as well: In some ways the continued discussion of this topic reflects the fact that we are moving from one equilibrium to an other. I still remember the discussions we saw before we moved to 3:2:1. Although it may soften the argument to start with my personal conclusion, but it may be easier to read: My vote is strongly in favor of 1:1:1. 3:2:2 can also be a solution for the next interval of 2-4 years (effectively the difference to 1:1:1 is not that big). (And actually the problem raised by others with the time horizon of 2.3 years for 3:2:2 is not a big deal - we have only three meetings a years so whether we plan for 6 events or seven events shouldn't break anybody's brain to solve that.) Now for the reasons: 1. First, the location _is_ a significant barrier to entry for newcomers and other contributors. Optimizing only for the current status quo does create a strong perpetual cycle of self reinforcing structure of contributors from the favored location(s). Consider that contributors usually start as newcomers, attend several meetings, then write a draft, join more WGs and maybe chair a WG. But if you make it hard for newcomers to attend several meetings they are at a severe disadvantage to become future contributors. Part of the value of the IETF derives from its global scope, it's global acceptance and the wide range of ideas and involving the best minds on this planet to solve our problems. If we exclude people from this process we deprive ourselves from part of this rich resource. This leads me to the first part of an answer: we need a wide inclusion and allow future contributions from all areas (which requires meetings on different continents to some degree). 2. Cost for contributors: Having said that, of course we need to consider the costs for the current contributors doing our work today. For most current contributors their experience allows them to judge and to justify higher travel costs (as they come by long-distance travel) much better as they can already demonstrate the benefits of working with the IETF to their employers or for themselves. 3. As I said at the beginning, we are not in a stable equilibrium. Many of the arguments to keep 3:2:1 or for 2:1:1 may be true today if we would be, but this is not the case. We are moving from a mono-polar (US centric view) to a multi-polar and someday hopefully truly international work form. Before we moved from 4:1:1 to 3:2:1, the percentages were not yet fully in favor of the move either, but they significantly shifted over the last years. And they will continue to shift further. So we should consider that although currently 1:1:1 is not representing the current ratios, it may well represent the future ratios if we allow them to go this way. And that is what we should do. We should avoid to lock ourselves into a biased situation where travel costs reinforce the status quo and deprive us of a future wider international participation. So my proposal would be to balance the cost pressures of current contributors with the future contributions we expect from the different areas and choose a future oriented ratio with 1:1:1.
