Speaking as one of those independent consultants who, in the last eight years or so has attended every IETF meeting and paid all of my own costs to all but one of them (I had a registration fee waived once), and who was previously sometimes in the approval loop for corporate permission/sponsorship by others... If you want to go very far down the path you outline, you have to ask some questions that we have never asked and to which you/we may not want to know the answers. Examples: * Are there differences in different regions as to the ratio between those who are really participating as individuals and those who have corporate sponsorship? * If a corporation typically sends a lot of people to IETF but has overall cost constraints such that some choices of location might reduce the total number of people they sent, would that really reduce overall IETF effectiveness? Put differently, if such a corporation cut participation by Go-ers and various other forms of tourists and damage-preventers, leaving only those who actively contribute to the IETF's work, would that result in a worse or slower IETF product? * Coming back to another optimization discussion, would you want to adjust the weightings to favor those who are actively participating in a variety of IETF efforts over those who come to participate in one or two WGs and otherwise have spare time? * Remember that, for some people and some companies, the perceived costs of having someone with real design or product responsibility away from his or her desk may completely dominate any travel or registration costs. For other situations, that is definitely not the case. If one really wants to look at costs in depth, I would also point out that the Beijing meeting has a de facto minimum registration fee (registration + minimum visa fee) for US citizens of $775 and one for most others of $110 less. Because of differences in visa policies in other countries, meetings in other locations may impose differentials disfavoring other groups. And all of that is in addition to points made by others including that distance is not a very good surrogate for overall costs (or even airfares), that some of these optimizations may pessimize overall attendance or attendance by active participants, etc. So, while I might personally benefit from the sort of revision in formula you suggest, I have significant doubts that you can really make those measurements and that optimization correctly (for some sensible value of "correct"). Unless "we" can figure out how to control overall costs and the cost-efficiency ratio for just about everyone, I know I'm going to need to stop attending meetings face to face for which I don't have (or seek) sponsorship. That is just how it is; I'd much rather see the focus on controlling overall costs to everyone, examining locations and meeting schedules for their consequences on time away from home (which translates into lost billable hours for some of us and irritated families for some others), whether a meeting in a particular location requires making a tradeoff between staying in an inconvenient place and staying in an expensive luxury hotel, and so on. john _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
