OneWorld is the name of the script I'm developing to replace my old SceneSetter project - basically, a way of synchronising the FG environment over multiplayer. Within a couple of weeks, I hope to have a host-guest (or server-client) system working so that the host can set (and, if appropriate, change) the time offset and weather scenario for all guests/clients running their scenario. This would hopefully make verbal synchronisation of time and weather a thing of the past on FlightNights. There are tons of other possibilities, like scoring in competitive events like Fightertag, for example.
This post is just to get the thread established. But I hope it will be available for FlightNight flight leaders to use if they want to within a couple of weeks.
