A recent article by ArsTechnica mentioned:
Does deep packet inspection mean the end of the Internet?
QUOTE
Deep packet inspection (DPI) gear has always been marketed to ISPs as a way to earn more money by scanning Internet traffic and charging more for various services. Want to game online? Better upgrade to the "Gaming Xtreme!" plan. Want to use VoIP? Prepare to open your wallet. Watch much streaming video? Well, it would be a whole lot smoother if you just paid another $2.99 a month.
DPI vendors haven't tried to hide this; one company's marketing literature suggests that it can help "reduce the performance of applications with negative influence on revenues" (e.g. competitive VoIP services).
ISPs want to avoid becoming a low-margin "bit pipe"—a dumb communications network that just enables companies like Google to make bazillions of dollars. And one good way to do that is to sell expensive services, using DPI to identity and categorize Internet traffic, then degrade or prioritize protocols and applications to fit the service profile.
It doesn't happen much in the US, where consumers are accustomed to one monthly payment covering access to every service on the 'Net without degradation. ISPs therefore deploy DPI gear at their peril, as Comcast found out when it begin forging TCP reset packets to slow BitTorrent uploads. Consumer reaction came quickly, and FCC oversight soon followed.
The same thing happened with NebuAd, the company that hoped to monitor ISP networks to deliver targeted advertising to end-users based on their surfing habits. After outrage and congressional involvement, the company lost its CEO and dropped the controversial approach.

What does it means?
It means that evil isps now have the capability to downplay competition and ruin other service and application providers if they wanted.
Take for example there are many VoIP providers such as Pennytel, VoIPStunt, Jaring OneComm, RedTone all competing with TM's own solution TM BB Phone.
The network operator has the capability to put all its competitor's flagged packets to low priority while placing their own in high to make it in such a way that all the others will experience severe lag to obliterate competition.
Same too if they want their customers to have excellent IPTV reception, they can choose to put Hypp TV flagged packets as HIGH PRIORITY so that people can access the server with low pings as such.
Please help forward my question to them and ask them whether they'll implement such things in their network transparently.
