I realize the originator didn't end up using screen (and said why), but 
just for completeness, I have this little shell script I wrote long
ago.  I have no idea if it's even needed anymore..

#!/bin/sh
if screen -ls|grep Detached > /dev/null; then
        screen -R
else
        screen -R -d
fi


which I call 'doscreen'.  The help for -R says
-R            Reattach if possible, otherwise start a new session.

So maybe that check isn't even necessary... but again, I don't actually
use screen too much anymore (though once in a while I run into a situation
where I wish I had started something in screen).
