Or you set up a 'call out' at predetermined times.

How you achieve the connection is what I would have to research, but 
I'm sure it must be possible - and not too difficult.  I would imagine 
(say) an SSH server running on your home computer, and a console in the 
shell account from which you could log in to your home computer.

As you still won't be able to get a public IP number for your home 
computer (only for your communal internet connection), I think routing 
would have to involve the shell account for every packet.

More technicalities I'd have to research!
