Also the new DOCSIS standard will try to address this issue.

How do you get your cable phone to work when the electricity goes out? Although I would get a cable modem if it were available, I would not trust my only access as quickly. I would certainly love a second line, though. I used to have teenagers, and would have thought a restricted local phone just for them would have been great -- wire taps or not.

>Well ... not as easy as your current phone line. Those familiar with the current phone system know that they could walk right up to the outside of your house, and clip a phone on to the "lightning protector" at the phone box ... and either "tap" or use your phone! >The same can be done at any of the little green "posts" throughout your neighborhood ... You just go right up to the house, and clip on the phone. Well, first you need to get passed my dog, and then you better have a warrant. With a cable, you could do the same thing, from comfort of you own home, and yes legally. In fact you can read the data from any point along the cable segment, before and after the intended destination. When a packet is transmitted across the cable, it does not make a left turn and exit the cable at your home. The data is transmitted across the cable just like the television signal, and is received and processed by every modem in the subnet. >On the cable system, you'll probably have to have a known good MAC address, on the Ethernet adapter in the computer, for that exact segment. Then get an IP address ... and possibly know some other authentication. If I pay my monthly subscription each month, I will have a valid MAC and IP. Now by running a program such as "EtherPeek", I can legally capture and store every packet from every computer on the subnet. Encryption will be the only defense, and may be adequate protection for the home, but a business will not rest well knowing that the companies conversations are being monitored by the competition down the street. Well ... not exactly. A TV is a "passive" device ... not two-way. Although in many cable systems the computer communications are currently not "secure" ffrom your neighbors, I am able to utilize technologies like VPN (Virtual Private Networks) to encrypt my communications from end to end. Many of the gateways are also building this feature. So again, even if they got to the line the data can be encrypted. I believe you are missing the point. The cable lacks the physical separation between stations. VoIP would have be delivered just like a pay per view movie The "Phracks" will scrap their Red, Blue and Black Boxes, along with their 6.5536Mhz crystals, and live happily ever after in packet heaven.
