Let's try this and see how it goes...
I created a user 'tipcuw' to allow persistant connection and
shared access to the testbed.  So insteaded of 'tip'ing
directly to the nodes run:

	screen -r tipcuw/

to connect to the existing 'tip's.  (the / is not a path
separator).  

You can see who else is connected to the session and what 
window they are in using the screen command C-A *

This screen session contains one window for each of usbcuw0-6
in order, so to get to usbcuw3 type C-A 3 (provided nobody 
has altered the screen session).

If the session is not running, it can be started by running 
screen as 'tipcuw' with:

	sudo -H -u tipcuw screen -m -d

The -H is important, otherwise sudo won't change $HOME and 
the correct screenrc will not be used.  The '-m -d' flags 
simply start a detatched screen.  This session is not started 
automatically, but it should only go away if we reboot.

Another admin issue is that the user access list unfortunately 
can't be based on a group, so new developers must be added
to tipcuw's screenrc as well as the appropriate /etc/group.
