Chris,
I think your Hilton discussion forum proposal is a wonderful idea, particularly if you are present to chair it.
I don't always agree with your views of USA airspace. I still think that we should have airspace and procedures that suit Australian conditions, environment and culture. I'm sure this is possible while still being ICAO compliant.
Best of luck with your Hilton seminar, sorry I can't attend. With some balanced, logical thinking some real, safe, expeditous and meaningful airspace reform might be achieved.
