Think about this way: Cable is like having a neighborhood network running through a hub. DSL is like having a neighborhood network running through a switch. You *will* hit bottlenecks in both, but the number of people on your block with DSL doesn't degrade your service noticeably. (The number of Speakeasy clients on the Philly CO could eventually choke me up... but it hasn't so far, and Speakeasy's quite responsive. DCAnet seems to be very similar.) With cable, when your neighbor gets a cable modem, your bandwidth is effectively halved any time both of you are on. And so forth. (Um, that's an exageration, actually, but I think you see my point.) -- gabriel rosenkoetter gr@eclipsed.net Attachment:
