There are several methods one could use. propose one. meetings 80 81 82 85 and 86 already have locations so I'm guessing the experiment starts in earnest in august 2013. > Ross > > -----Original Message----- > From: ietf-bounces@xxxxxxxx [mailto:ietf-bounces@xxxxxxxx] On Behalf Of Marshall Eubanks > Sent: Wednesday, September 01, 2010 10:56 AM > To: Scott Brim > Cc: Adrian Farrel; ietf@xxxxxxxx > Subject: Re: IETF Attendance by continent > > On Aug 28, 2010, at 1:25 PM, Scott Brim wrote: > >> On 08/28/2010 12:28 EDT, Adrian Farrel wrote: >>> And even closer to 3:2:2 ? > > I think that people have unreasonable expectations about what we can do here. > > There are 3 meetings per year, and 3 meeting regions being considered, and we are generally considering something between 1 and 3 years out at any time. > > Suppose that the time horizon is 2 years.
