After reading (at least most of) the discussion that has arisen from this, I've had another thought which would use the wire already ordered -- although it does involve "special hardware". Maybe you could set up what would amount to your own two-point telco: Option 1: Put a T1 frame-relay box at each end. I don't know how far a T1 can run without a booster of some sort, but I'd think it must be more than a mile or it would not have been commercially feasible. Option 2: Put an ordinary DSL modem at one end and a DSLAM at the other end. Again I'm not sure what the range is, but DSL used to be referred to as the solution for "the last mile" from the telco to the customer so it may be up to the job. AFAIK neither of these really needs the signal quality of Cat 5 -- they both should work just fine over Cat 3 -- but surely the higher grade wire can't hurt (and it may increase the usable DSL distance).
