The more TV that becomes availabe free on the tinternet the more the ISP's will have to deal with much higher bandwidth usage by the average person.
All those on bandwidth limited connections, who DON'T monitor it will get a massive surprise (an email and threats from their ISP saying they've gone over their limit) when they start to use things like the BBC iplayer and such like.
It's going to need a total rethink by the ISP's on how they sell their products, thier prices and bandwidth limits.
Hopefully it will mean the same prices but bigger bandwidth limits as they fight with each
