Product amplifier
The concept of creating custom sound and audio using an amplifier with sliders is a common concept. Certain slider settings are even associated with specific genres like pop, rock, classical, voice, flat, etc.
Internet broadband products are no different. There isn't a single product that will suit the market and debating about uncapped versus usage based products misses the point. That is but a single variable slide of any Internet broadband product.
So how does a product amplifier look for an Internet broadband product?
The sliders with variable settings are:- Price - is directly influenced by the position of the other sliders.
- Speed - a slider that indications throughput.
- Symmetry - an indication of the difference between upload and download speeds (typically a business requires better upload ability).
- Connections - the network connection count, i.e. how many sessions (e.g. browser windows you can open).
- Bucket/usage - an indication of the bucket size with uncapped being the extreme.
- Time period - used to indicate peak times and off peak times.
- Availability - amount of expected downtime, often categorized as gold, silver and bronze.
- Content - a master slider consisting of a subset of sliders that adjusts content. This content can include: video, browsing, email, P2P, VoIP and social network as an example.
- Bursting - ability to go beyond the expected throughput or usage limits.
The product amplifier is a method to create very cheap or expensive products dependant on the consumer appetite. As with audio, consumers will have genres where a certain slider setting will be preferential for a large common base. These product slide differentials are achieved using products like a service control engine.

You can find Packet Pushers here.
I have always been of the opinion that layer 2 is acceptable in this application and there are no real requirements for layer 3.
