I got the 4Gb number very crudely. I assumed you could fit 100 6Mhz channels on a coax line each one providing 40Mb. Im sure that Dave Homes calculation of 2.6Gb is based on a lot more detail than that. My only real point is to show that there is a lot more bandwidth that could be created if they were not used up by three channels of HBO showing the same thing at different times or a channel decidated to the local community college. How about the channel that shows a TV guide and/or the local time & weather? Lots & lots of wasted bandwidth. HFC can stretch a lot further than the public realizes. I'll bet newer modems standards could also squeeze a little more out of the 6mhz bandwith and/or should be able to get more than double out of two consecutive channels. Does anyone know if cable modems are running real-time compression algorithms? You might also be able to enhance performance by using more intelligent networking algorithms than collision detection which degrades rapidly when heavily loaded. It ain't as pretty as pure, but this kind of stuff is a lot more likely to happen first. Feedback from anyone more informed? Eric
