>Here in the states, if you go with a Comcast router, you get pretty much the same thing, except anyone parked outside needs to be a Comcast customer to use your signal.

That's the same here - only BT customers can access the hotspots. I've opened up mine but I don't think anyone has ever used it. OTOH I've hardly taken advantage of my access to other routers. Don't think there is a real security issue since, as I understand it the two channels are completely separate.

I own my cable modem and router so I have full control. All access, including Guest, requires a password.

>>I'll take a closer look at that. At the moment I need some way of reliably sending CCTV over about 100yds. None of my current Wifi stuff seems capable :-{
