Yes, thanks for the heads-up. I saw that when I checked it out.
Firewalla does a similar thing, using their own DNS cache. For privacy,
though, they do NOT look inside the 'data stream', and, as a result,
can't block as many ads as a service that looks inside your data.  I'll
settle for that trade-off, though. :-) I also saw several services that
do similar things - you just have to change your DNS on the comp or
router, they do the rest. I'd guess the free ones like to look inside
data to see what they can sell. :-)

I actually wanted a firewall, and got Firewalla. I'm finding it does
other useful things as well. They have newer gigabit hardware that can
do network segmentation, etc, and is also a router. It is tempting
me. :-)

Thanks...
