Current Qwest customers can expect many service enhancements in the future to keep the stock price ever increasing. Such as a 40gb download limit, 1 dollar per gigabyte overage charges, increased internet connection prices for existing customers and the offering of 3 month deals for new customers so they can still advertise the lower price, etc. And Qwest will blame all the "enhancements" on the cost of network upgrades to continue to provide their customers with the quality of service they expect, instead of just admitting it's because of the low stock price and the network is more than capable of handling all of the customers traffic.

They're not going to institute a 40GB cap, and no provider's network can handle an unlimited amout of traffic.
