fwiw, Windows has other mechanisms to share resources between processes. To share/pass sockets, you can use WSADuplicateSocket. For shared memory and other resources, DuplicateHandle API. (you can also share other things like D3D textures etc. those mechanisms are used to enable -display dbus on Windows efficiently) -- Marc-André Lureau
