you can auto-start a program of your choice directly from an ssh
command. for example:
$ ssh -t myhost screen -R -d
will connect over ssh and then run screen to auto detach then reattach a
running a screen or start a new one if not.
you can of course name your screens so you can connect to
mycompilewindow or mycleverideasvimwindow

alternatively, and if you tend to use a mobile device for ssh you can
but something like in your .bashrc
if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
  screen -R -d
fi

which would check to see if ssh variables are set by openssh i.e. it is
an ssh session and then run screen for you
