It is true it does NOT eat into your bandwidth. The bandwidth has been increased quite a bit in cities over the last few years, for example, in the city I live in, we now have 16 channels for broadband. As for the hacking into your home-network, I love how the media has misconstrued this. It is a second, entirely different provisioned network. It is segmented and there for not seen by the other network. It's just like the routers you can install that have a guest network. If you're connected to it, you cannot see the private comps on the other network.
