Picked this off the Fool's evening news:

...breathless press reports overstate what is workable in real life, according to communications engineers. What works on a clean phone line in a laboratory doesn't necessarily work with multiple bridges and interference in the lines under San Francisco or New York City. Many engineers believe that real-life working conditions are much different than laboratory benchmarks cited in the article, but they also believe that DSL multiplexing is superior to cable bandwidth solutions, which are necessarily shared connections and bog down with each additional user hooked into the network. The article leaves DSL watchers rather unimpressed but interested that someone inside Microsoft would be hedging on their huge investment in America's cable plant. Investors bummed out that they missed the re-birth of the cable industry might want to take note.

I'd like to point out that ATHM has addressed the "shared connection bog down" with their RDC and headend caches. Even so it is still an issue for further development in higher quality fiber and better transmission technology. DSL multiplexing is only superior in a waveguide that has properties commensurate with fiber. There is hyper -fine copper that can accomplish this at 20 times the existing cost and it would have to be installed over all existing copper. But even this is the absolute limit of copper. If you go to better quality fiber, game's over.
