Andrew,
Thanks for raising this.
While the stated rationale in S 2. is to spread travel pain around,
I don't really think this gets us to 1-1-1-*.
First, if you look at historical demographics, over the past 12 IETFs,
we have 23% Asia, 26% Europe, and 42% NA). Put another way, the last
time we had > 1/3 Asian attendance was IETF 94 in Yokohama, and the
last time we had less than 1/3 NA attendance was IETF 79 in Beijing.
So, a policy that was designed to match per-continent attendance would
be more like 2-1-1-*.
Second, continent is not a very good proxy for travel pain, both
because Asia is so large (for instance, the shortest Tokyo to
Singapore route is 7:25 out and 7:10 back (on JAL) and the shortest
Tokyo - Honolulu route (ANA) is 7:20/8:10, so not really much
different at all) and because flight connections are such a big
contributor ( for instance, SFO-BKK is almost 20 hours, whereas
SFO-NRT is 11).
Bottom line, if this is supposed to be real requirements rather
than just aspirations, I think it needs a rethink.
