Crap Rules? No Net Neutrality will change the Internet
First, there's no such thing as unlimited bandwidth and it's nothing to do the Net Neutrality.
Net Neutrality has nothing to do with bandwidth caps or traffic shaping to _control what you do_ over your connection, that's do do with your supplier selling you something that they cannot afford to supply, so have to control how much you use until they can afford what you are using.
Net Neutrality has nothing to do with traffic shaping to ensure a _providers network operates effectively_. They might lower bandwith to bulk transports protocols like FTP or lower priority to SMTP as it's a background process you don't usually see, so that they can reduce latency on SIP/Skype so the quality is good when you phone your mother in Spain.
People, companies, whoever, they are pay to _connect_ to the Internet, Net Neutrality means that the carrier will then let your packets move across their network on onward over other networks communicating with your destination, whatever and wherever it is.
Net Neutrality means that BTel should not, for instance, introduce latency into SIP/Skype so that the quality is so bad that it doesn't work and you are forced to use your BTel telephone to call you Mother and pay again for what you should be able to do over your Internet connection. NN means that you should be able to watch smooth iPlayer or Youtube content on your Skyee internet connection, without NN Skyee might block or more likely limit bandwidth to force you to subscribe to their premium TV content. Tescow could block access to other major online shops on their customers broadband. Vorgin might interfere with SIP,Skype,iPlayer... Oh, thinking about it, they _all_ might do _all_ of this as they all offer the same premium services and want to maximise profits and monetize their customers.
The broadband providers are all taking this to the next level, they are trying to make the places/services you visit pay as well. Want to watch video, well you'll only be able to watch video from sites that pay your provider. Want to go shopping, only from sites with higher prices as they have to pay a margin to your provider to allow you to access them. Want to send email, OK as long as you don't mind the SPAM that your provider is paid to transport to you. Have you got a website? You might have paid for a premium hosing account from your web host, but the performance will be poor as your web host isn't paying your broadband provider to "prioritise" your content over the broadband network.
Business exists to maximise profit for their investors, they have a duty to thier investors to make as much money as possible, without NN they will do everything they can think of to moneytize you, they might even spy on your connection, machine read all your emails so they can fill your screens with adverts... oh forgot, they tried that already!
