Ideally cloud layers, thickness, types etc. should all be the same. Same for wind and turbulence. I'm sure that we can do it. At least by ensuring that initial conditions are all consistent. > At this moment, I am skeptical about getting WX updates from the server. > Does server-side push of WX update to everybody make sense at all other > than > the fact that this way it might be possible to cut down on the traffic > to the metar NOAA feed?

They certainly will fly differently if they don't get the same weather by some means. Have you now countered your own argument? We could make life interesting by having 2 duty runways crossing each other, and no ATC. > Another downside is that everybody > needs metar from different places, so in the worst case, with N > players flying in N different places on the Earth, the total data > sucked off NOAA is the same, yet the server now must be the > one doing it all.

Then the load on NOAA is the same in either case. In all other cases there would be a (small) saving. Don't forget, in FlightGear realism is everything.
