Ssh has an implementation for this. It requires proxying. If we have a developer for this, I can give some coaching.

This is apparently a common problem that lots of people complain about: A
user reconnects to an old screen session, but they can't run X11 apps, because
the DISPLAY variable in the session is stale.

I notice that gnu screen correctly picks up the terminal size, type, and
attributes from the environment. So I don't see why the same can't be done
with the X11 DISPLAY variable. (Although there perhaps should be a command
line option for screen to do this, in case the user really wants DISPLAY to be
something different.)
