They can regulate it!
It amazes me that they still have not broken the Internet. There are little bits that are broken, like using skype on a mobile phone, that does not work as it would on the real Internet.
However with all the big ISPs gobbling up the smaller ones and many of them talking to people like Phorm, it may soon break.
When I say it will break, I mean that instead of being able to visit any website or any server in the world, we will be restricted for our own benefit and safety.
The Internet does not really have a bandwidth problem that can't be solved, unlike terestrial TV which is limited by the radio spectrum. With the Internet another cable can always be added where there are bottlenecks.
The Bandwidth problem the Internet does have is that there is just too much to look at and too much to control.
The Internet also has a credibility problem with the TV watching News Paper reading public. "I read it on the Internet" does not carry as much cred as "I saw it on the News". The responsibility in deciding if a story should be believed lies with the reader. However with TV you may not get the chance to see the story. I personally believe that you are more likely to learn the truth on the Internet because it is unfiltered.
I think part of the Internet's credibility problem comes from the TV and News Papers themselves. Oh don't believe stuff on the Internet, read it in our Paper.
Perhaps the government could offer some sort of kite mark indicating that the site is regularly checked for standards. However that's going to cost someone and I can see many sites not wanting such government approval.
I expect the first people to want Filtered Internet will be companies who already net nanny their employees usage. Then parents will want it. Then the big ISP's will implement it by default. Then Jacqui Smith will say that all Paedos have to be on Filtered Internet. This will be the IPv6 version which requires the thumbscan public key address packet.
Eventually no one will look at your old style website on the old IPv2 network because they won't have access. Only a few hackers and pervs will still use it. You could move to IPv6 server but it costs a lot and you need a licence.
Maybe time to leave the Internet.
