A fun twist on tiered internet, or, is Microsoft paying for this?

It’s coming to light that Comcast appears to be interfering with Lotus Notes traffic, in addition to other packet types. This isn’t surprising and is perfectly in line with a company that wants a tiered internet so people “don’t get things for free”. But what if they actually were to put packet transfer rates on the open market and let Microsoft (creator of IBM’s primary groupware competitor) and IBM duke it out. Instead getting people to pay twice for service, they could actually extort many multiples of that.
Sure it’s a conspiracy nut accusation to seriously think Microsoft would be behind this, but the what-if is the interesting part. It’s a much better business model. Why as the consumer and producer to pay a rate on the service they want, when you could inflate that price by allowing the competition to pay for anti-service?
