Re: DSL...The Nature Of The Beast
DSL isn't "always on" unless your provider hands out IPs via DHCP, which many don't. A lot of ISPs use PPPoE for their DSL service, which requires you perform a very painless 'dial' that takes no longer than 2 or 3 seconds. However, most routers can be set up to keep your PPPoE connection alive for however long you specify. So it's actually a virtual always on connection.
As for the distance thing, it gets rather complicated. Generally speaking, you're fine if you live under 15k feet from your local CO, or remote terminal. You're looking at 1.5Mbit - 3Mbit at that distance, and that's providing you have decent premises wiring.
