It's time to start considering an Internet connection, rather than a phone line, to be the "typical" communications infrastructure found in homes and businesses. Ask any building manager -- would they rather connect their alarms and lifts to a bunch of dedicated analog lines, or to the building LAN? Sun Microsystems (RIP) figured this out 20 years ago. They said [http://java.sys-con.com/node/35818] that we need to move from a "dial tone" world to a "web tone" world.
Sun was right about a lot of things but they were either ahead of their time or didn't execute well (take your pick). Remember their "network computing" push? Well guess what, kids: we're there.
