The biggest problem is middle mile. That is where the money needs to go. You need something to back haul to the interwebz. There is a lot of fiber in the ground already,
Another possible way to solve the middle mile issue would again be to use the copper plant that's already in the ground. Unlike fiber, the copper plant is *ubiquitous*: I don't know of any place in the 1st or 2nd worlds that doesn't have copper pairs going to it. Also AFAIK T1s are available everywhere too: if you order a T1, they'll deliver it to you regardless of how deep you are in the middle of nowhere, although I suppose there likely are extra surcharges involved. Granted, a T1 at 1.5 Mbps may not be much for backhaul, but what about bonded T1s? Bond 4 of them to get 6 Mbps symmetric - not too bad in my book for a rural community. And again using SDSL instead of T1 offers a cost reduction opportunity. One could get that 6 Mbps symmetric for much cheaper by bonding 4 SDSL circuits running at 1.5 Mbps each instead of T1s. There is a Covad DSLAM with SDSL capability in virtually every CO in the country, but they serve out a whacky flavor of SDSL/2B1Q. I have good reason to suspect that I may be the last person alive on Earth who knows how to make CPE for this flavor *and* who cares about such things.
but there are numerous layer 8 issues with getting to it most of the time. Solving those is an exercise left for the reader.
Layer 8? Assuming that layers 8, 9 and 10 are management, financial and political, respectively, the issues that keep me from being able to build that Covad-compatible bonded NxSDSL CPE device lie at Layer 9. Anyone interested in helping me solve those issues? MS
