yeah, barrier is ok still between two xorg linux machines using barrier but to do it between windows and linux you gotta pay for this one
barrier has been abandoned, and neither support wayland
this is one of the reasons i hate wayland so much, all this energy is now going towards making it work meanwhile still lots of reasons to stick with xorg and as a result the net effect is half the progress on linux GUI progress, plus fucking Gnome project went completely off the reservation with gnome 4
