I've been working on something similar but not quite got there, your solutions have solved my problem so here's my suggestion:

ssh -t server.com "screen -S foo -rd || screen -S foo"

This just tries to open the existing screen named foo and if it doesnt exist, creates it. I'll put this in a launcher on my laptop, so when the wireless network goes I can just open where I left off.

Just noticed that the default screen shell is a bit weak, so an improvement which sets up your home environment a little better is:

ssh -t server.com "screen -S foo -rd || screen -S foo bash -l"
