That being said, the ICCCM defines the WM_CLIENT_MACHINE property:
WM_CLIENT_MACHINE(STRING) = "poincare.devel.redhat.com"
and the freedesktop.org WM spec defines the _NET_WM_PID property:
_NET_WM_PID(CARDINAL) = 23397
So, if the toolkit that creates the window supports these
specifications, you can find out the client machine and process ID.
