If you install IPCop on (say) a P75 you can leave it permanently turned 
on (via a UPS, especially in the bush). Ditto your dial-up modem.

When your father-in-law wishes to play on the Internet he:
1. Fires up his Windows box (if necessary);
2. (Double) clicks the IPCop icon;
3. Selects the button marked "Connect";
4. Completes the Password Dialog box; and
5. When his browser tells him he is "connected"
     he can shut down the IPCop application and
     get on with his surfing.

He will disconnect via the same procedure.

My IPCop firewall/router is only turned off during thunderstorms and 
long mains power outages.
