Cannot comment on the wheather :)

Another option you can consider if you have a server or mostly on 
computer on your side, is to use openvpn. As long as you have port 
forwarding in place on your side, the client at Margarets would happily 
connect through a NAT or other firewall, as most of them allows pretty 
much all outgoing traffic.

I do not know if ssh will keep re-trying. openvpn will do that. Most 
distributions support openvpn as a service.
