paid for by digital cash. Such a means of exchanging print, audio, video, or any software might be virtually impossible to censor. Would it be possible to build such a network using current cable systems?
It is a reasonable bet that all data into the home will come on cable systems which means they require encrytion anyway.. there are bridged, not point-to-point... And other traffic like mobile voice and data will use some RF technology... which also requires encryption... Existing cable systems are now running 1 gigahertz of bandwidth and I had presentations from TW staff indicating 2 gigahertz is easily reachable.. Figure 2 gigahertz of bandwidth (split between analog and digital services) in each neighborhood and a ATM switch pulling those signals back to the "head-end/central office" via fiber, and you have the cable system of the future.. (e.g, for the next 5 to 20 years).. /hawk
