Even with fancy ($300-1k) LRE/dsl extenders, your limits are somewhere around 7km. Not exactly something you can expect some consumer to jump on the costs of. They expect the service to cost less than the computer they are going to attach. > I will happily agree that it would be nice to have higher upload speeds > than DSL generally provides nowadays. What are cable upload speeds like? I think that with the current market environment the only choices will become some sort of municipal fiber builds (most people can accept the cost via their property taxes or other means that may even be tax deductable for them personally) or possible regulation of delivery of "internet" services in the same way that delivery of POTS services are necessary. Last time I talked to someone at my PUC, he was griping about the lack of POTS services in the state. Even with all the USF and other monies, tarrifed POTS services are not available. I think this says something. Me? I see a resurgance (as long as regulatory - CALEA & other costs) in the local SPs coming as opposed to the cable/dsl cartels. Most folks are thinking wireless these days, but I suspect that once they realize that the cost of putting fiber across their property is actually low enough, a number of these local isps will negotiate their own cabling paths. This may also have some problems as if they're "good enough" we may see the telcos and cable co's vying for access to their facilities to deliver tv/voice/data as well over it. Either way, the challenges in this space in the coming years at the high end (100G and faster) as well as how to deliver content at a reasonable speed to the end-user networks will make for a fun time in networking. - Jared -- Jared Mauch | pgp key available via finger from [email protected] clue++; | http://puck.nether.net/~jared/ My statements are only mine.
