Some picks ago I called attention to shared virtual desktops for gaming purposes. Programs with which you can make a kind of tabletop on your computer, and then share it with others anywhere on the world. As long as you're connected to internet. That way, you can play a role playing game even if you're all in different outbacks.
The virtual online desktops I linked were quite professional and expensive ones. But what I failed to notice then, is that there also are free, open source products which claim to be just as good.
Open RPG is one, which you can get in several flavors. For windows, linux, or python (and then on any platform). Some find the Traipse implementation even more user friendly. Have a look, see if you can install them, and organize a game with players in Wellington, San Diego, Canberra and Johannesburg.
