Drifter, I'm not familiar with the ADSL. Maybe the dish is the way to go. How would you be able to seen back over a dish system though? Somebody out there with more info and expertise? I'm at my limits for the time being, until I can do some more research. JAC ;>)

ADSL vs cable (off-topic, but perhaps of interest)... ADSL and cable topologies differ a bit, but they ultimately run into exactly the same bottleneck - bandwidth out to "the net". With cable, you are sharing a pipe with all of your neighbors. It's just like being on a LAN in an office. So, actually, you are NOT even "exclusive to the neighborhood node". If it's properly-sized, no problem, though. Now, the shared aspect of cable can be a problem if everybody is streaming video at once, but both cable and ADSL have the same bandwidth problem if that streaming is going across the external Internet. With ADSL, you have an exclusive pipe to the telephone exchange. You aren't sharing it with anybody. But, once you hit either the neighborhood node or the telephone exchange, cable and ADSL look pretty-much alike. At that point, you hit an IP router or switch, and you start sharing big pipes that go off hither and yon carrying yours and a hundred or thousand other customer's packets off to Boston or San Francisco or Peking. All these pipes within and between ISPs need to be properly-sized for it all to work. Cable has tried to deal with the bandwidth crunch - and been pretty effective so far - by using proxy servers at the neighborhood node level, so when your neighbor downloads the lastest version of Netscape (or views the ZULU thread on SI), and you come along later to do the same thing, more likely than not you'll get a cached copy of it rather than going out across the net to get it. Same thing can be done with ADSL, though the companies offering ADSL have been less agressive in this regard. There, in a nutshell, is the ADSL vs. cable bandwidth issue. I think it's six of one, half a dozen of the other. So far, cable seems the winner on price, particularly on installation costs, though perhaps we will see reductions in ADSL prices.
