I am also using screen to keep sessions open on my personal server.
Additionally I am using Key based auth for SSH connections with no
password fallback (No Key = No Entry). I find the solution works
reasonably well for me and offers a little more security.

Perhaps that could be included in any demo especially the pitfalls of
turning off Password auth before you validate keys when administering
remotely. (Yes had to head to the bunker to fix it on the terminal)

Different problem.  
I was scp PUSHING files up to my web server.. The RR connection dropped
with locked up the running scp protocol session.  rsync was a good way
to "pick it back up" and continue the copy.

What you're talking about is being shelled into a place (like my web
server) and having screen keep & hold my shell session for me.  And
yes.. losing my ssh session to my server THEN is saved by using screen.
I use screen on my server to.  You can literally he in editing a live
HTML file.. lose connections.. and just ssh back in and <poof>, you're
still in the vi editor right where you left off.  Yes.. very nice.  If
any of you use ssh a lot and are not familiar with screen.. it's a god
send.  I even invoke it from my .bash_rc so that automatically
re-connects to existing screen sessions. :) Simple & effective.  Maybe I
should do a session on that at XCSSA...
