The big news here is that Time Warner Cable could go nationwide here. Imagine having all the cable companies compete on a single nationwide platform, over the Internet.
They said it couldn't happen. Look at the carriers and the iPhone.
TV Everywhere has already allowed multiple providers to stream their channels over IP to multiple devices not directly on their network. Nationwide distribution by many providers is only limited by content licensing.
Some channels are available, not all, which becomes fewer and fewer as you move your connection off of your home connection and then out of the local providers network. A few channels allow nationwide access as long as you have a paying account with a participating video provider.
Take a look outside the US and you will find that a lot of tv providers have gone IPTV. I have a colombian IPTV box that gets me all the Channels from Colombia. ETB provides me all the colombian content I want at a 1/8th the price of a us service.
Just sucks when my settop died and I had to wait 3 months to return it !!! But the low price for content and the fact I can take it with me anywhere I have a network jack... is just awesome.
