nickels and dimes one, I'd want to return the favor
and charge them an exorbitant rental for housing and
powering their public wifi device on private property.
I could throw in (without even asking them if they
want it) an unexpected $3.95 monthly fee for
preventative dusting of the device "to ensure maximum
operating efficiency". Or how about a fee to ensure
that their public wifi device is not tampered with,
since they are now effectively regarding people's
homes as public spaces, and you know, anything can go
wrong in a public space.</div>

Yeah, I believe that. The APPARENT<br>

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>

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>

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>

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>

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>
