What do you meaning starting, that happened years ago.

15 million ip subscribers, 6 million voice subscribers, 30 million cable
tv subscribers...

Saw this today too. This is a good step forward for adoption. Without
going too far, what was the driving factor/selling point to moving
towards this trial?

SWAG: Comcast is a mobile operator.  At some point NAT becomes very
expensive for mobile devices and it makes sense to use IPv6 where you
don't need to do NAT.  Once you deploy v6 on your mobile net, it is to
your advantage to have the stuff your mobile devices connect to also be
v6.  Do do THAT your network needs to transport v6 and once your net is
ipv6 enabled, there is no reason not to leverage that capability to the
rest of your network. /SWAG

My gut instinct says that mobile operators will be a major player in v6
SWAG is wrong. Comcast is a major cable TV, telephone (VoIP), and
Internet provider, but they don't do mobile (so far).
