The OR, you could package a few terabytes of data onto magnetic tapes and fly them to your destination. You'd get a higher data throughput. Do not underestimate the bandwidth of a station wagon full of magnetic tapes speeding down the highway. > user has no choice but to wait for 24 hours for the next broadcast in > case he/she has just missed it.

Talk to them to reuse. I know there were plans with the dept of agriculture, something along the lines of regional programming slots for local farmers (anyone remember Amchi Mati Amchi Mansa?) -- "There is hopeful symbolism in the fact that flags do not wave in a vacuum." --Arthur C.
