For those of us that are already running triple play architectures and
working on the data analysis related to the bandwidth usage growth (in my
case over the last 18 months and adding services one after the other) I see
this with a different light:
I fully agree with the transaction latency syndrome, people are compulsive
customers that want to buy right now and you (as a service provider) want to
see to them purchase the service before they change their mind, just need to
look at the ringtones market to see how much people are willing to spend
within seconds for a piece of music they will replace in a few days/weeks
with their next favorite tune from the charts that marketing is feeding them
with.
Where I don't agree is on the bandwidth usage analysis, once you add the IP
based TV/VOD* services you will be carrying close to 5Mbps on average on
your network in the near future. Either for the one of the TV channels
(currently the market is talking about 2 concurrent TV channels down the
same pipe to an end user's home in the North American model or 1 for the
European) or the VOD. So agreed this is not Internet traffic but you will
need to carry it beyond your access termination device (DSLAM/CMTS/ Ethernet
switch) since the economics of the IPTV/VOD market and (current?) technical
scalability will prevent you from being able to have a the full IPTV/VOD
streaming (= unicast and/or multicast in this case) in each POP to keep the
traffic as local as possible. So anyhow within your metro area network
accessing and aggregating the customers the amount of bandwith required to
service all customers will grow quite a bit with IPTV/VOD services.
IMHO (of course)

*Triple play IPTV/VOD = IP packets carrying a video signal using (name your
favorite format) either as unicast or multicast stream. This excludes the
current hybrid HFC networks that still provide digital TV via an HF stream
using (insert your favorite standard here) and the Internet access and voice
service over IP. Anyhow they will migrate once DOCSIS 3.0 and the wideband
benefits have been marketed to all the cable operators as the "next big
thing" they need to have and hence run an IP only service for all the triple
play services.
