See this thread: display using unix-domain socket (was Re: fd passing for X)
It would be nicer to be able to do:
DISPLAY=/home/user/private/myX11displayXYZ x11application
Probably requires changes to:
libX11
: _XConnectXCB
: xcb_parse_display, xcb_connect_to_display_with_auth_info, xcb_get_file_descriptor
libxcb
