Don't see how it would be against the law. They're going to replace a<br>
device they own connected to a service they own with another device<br>
they own connected to a service they own?<br>

<br>
I don't know how they have implemented this, but it would be trivial<br>
to assign a 2nd public IP (or even NAT through a single<br>
neighborhood-wifi-network IP) for the 2nd hotspot and route all<br>
traffic over that. In that case, a user connected to that has the<br>
same amount of access as anyone else on the internet.<br>

<br>
Citation needed. The biggest limitation to your bandwidth is the<br>
traffic shaping comcast performs at their head end unit. If the<br>
"public" hotspot is shaped separately, then I don't see how it would<br>
impact your bandwidth. *Maybe* you could make an argument regarding<br>
wifi interference, but a 2nd hotspot on your device won't be any<br>
different from a 2nd device somewhere nearby.<br>

<br>
Actually, no, the prosecution still has to prove you did it (at least,<br>
legally), but yes, I suppose it could cause some headaches, unless<br>
they can look at wifi hotspot vs private network. Not sure how that<br>
would work.<br>

<br>
On this, I agree. This should be with the user's consent, but I don't<br>
see it as a big bad threat.<br>
