Getting information about currently working multi-attach'd terminal

[John Davidorff Pell]

Ok, so here's my odd request of the day:

Is there any way, or will there soon be any way, to get information 
from screen about anything by invoking screen in a shell script?

If yes, then is there any way, or will there soon be any way, to get 
information from screen by invoking screen in a shell script about 
which terminal(s) multi-attached to a screen session is currently 
viewing a given window.



What I'm actually trying to do is this:

I have my .profile set up to invoke screen automatically (if 
interactive) with -xRR -p +. This way, I can open a number of terminal 
windows, each pointing to a different window in the same screen 
session.

When I ssh into my system from school/work, I have to set some 
variables so that agent forwarding, X forwarding, etc work properly (I 
have a script which is sourced by my shell which does this 
automatically, based on information available at most-recent login).

If I have a terminal window open at home, ssh in from work, then return 
home to my already-open terminal window, it has now-broken entries for 
SSH_AUTH_SOCK and DISPLAY in its environment.

I would like to have a script which pulls some information about which 
terminal is currently viewing a given window, allowing me to figure out 
where that terminal is coming from (ssh or local), then set some 
(cached from login) settings appropriately. It would also allow me to 
remember the most recently used terminal for any windows that are not 
being looked at.



Tips and Tricks are appreciated!
