EARTHLINK LAUNCHES CABLE HOME NETWORKING SERVICE, according to this Reuters article. It sounds a little back-to-the-future to me, since it implies that that the networking will be off the existing home cable TV lines, ala the old days of 10-base-T networking on RG-6 cables. Of course, at 10 megabits a second, that will be plenty fast for most cable modems. And infinitely faster than “sneakernet”, of course.
Of course, support of multiple computers on a home network makes sense for cable modem providers. I spent a hellish 48 hours or so trying to figure out how to get the multiple PCs in our home to talk to our cable modem after @Home hooked it up in early 1999. Fortunately, Sygate eventually did the trick, and still does, to this day.
