It's also a science project that probably never will come to be any more than that. In any event, it just extends the lease, so to speak. It's still shared and asymmetrical. Shared isn’t necessarily bad, but why share if you don’t have to. Asymmetrical isn’t even necessarily bad, as long as its adaptively scalable. But it isn’t. There are lots of ways to extend the lease besides lightwire. There will be lots more going forward. Trouble is they’re all “month to month” lease extensions. Bottom line is if 64Mbps is sufficient well in to the future, the future of “broadband” isn’t very exciting. That's a pretty minimal amount of growth (arguably, very little growth is required to fill that pipe today), and growth that doesn't require much in the way of new value chains to support it. Surely 64Mb will be at or near one of the steps taken on the way to real broadband, but it’s just that—a step. These are the wrong kinds of steps to build though. They require you build a new house along with the new steps. Build the house only once. If we make a comparison to Personal Computers just to make a sweeping point: My 133 MHz Pentium (this was 1994 I think) cost half as much and had about 10x the processing power, 20x the hard disk capacity, and 100x the RAM of the 12MHz 286 machine I bought in 1988, if memory serves. Few would have ever predicted the need, low cost, or size of the market that would evolve for that P133 machine, back in 1988. Now that 133 machine is (and has been for years) a cobweb collector (an elementary school won't even take it for free). You’re aware what you can get today and the price comparison to that 1988 machine. I do believe there is some relevance in using the 12MHz PC as a comparative benchmark for where we are today in “broadband” and fiber optics. One of the problems with the above Personal Computer comparison is that you couldn't buy the 10x improvement at the same time you could buy the original...it took years of semiconductor process evolutions. You still can’t buy the 1000x improvement. But….. A person doesn’t even have to stretch to reach a 1000x improvement in so-called broadband as it exists today. It's not even bleeding edge anymore. It already exists today. With GbE/FTTH, for example, you could get a 1000x improvement over what’s called “broadband” today. Forget the cost comparison today--nobody's claiming 1000x for free or at parity right now--but let's revisit this comparison in about 5 years and see if the numbers don’t scale in a huge way. History is on our side. Yep, I know what you're thinking--you don't need 1000x today. That’s not the point. The point is no technological evolution is necessary to reach it...it already exists. Even the services to consume that bandwidth *exist* today but aren't deployed in any appreciable way. Going forward what scales rapidly is cost (in the downward direction) and by the time you *do* need it (just humor me and assume that you will at some point), GbE and all the network components will be a couple/few generations below leading edge and will be dirt cheap. Lightwire probably wont even make economic sense at that time since all its proprietary components will have far less "economies of scale" cost benefits, and it’s per-subscriber capabilities may not look very attractive either. That 64Mbps best-case Lightwire system supports about one compressed high resolution video stream. I have a hard time believing that high resolution video (and new reasons to use it) will gain no ground over the next 5 years and beyond. Too many forces are pushing it from all directions, both directly and indirectly. It is the catalyst. Watch for the chain reaction.
