If you have a forward on your firewall, you can tell the remote party "right-click on the VNC icon in the lower right, add new client, and punch in $MY_IP_ADDRESS" Their VNC service will connect to your VNC viewer.

You can also script it - I have a Cygwin service that I made that checks a website for a command to trigger a reverse VNC connection.

Doesn't work when your family is behind double NAT.

Why wouldn't it? It only relies on the ability to create a single outbound TCP connection; surely double NAT doesn't impede that?

If both parties are double NAT, then sure, you have a problem, but aside from that; as long the party you are connecting to doesn't -- it should work fine as described.
