No, but there are still a lot of opportunities out there which require hardware.
One idea struck me the other day: why not use your iPhone (or Android phone) as a home phone handset, when you're home and in Wifi range? That would require a specialized base station (perhaps running a stripped-down Asterisk) that recognized when your phone was in range, and would "ring" it on demand, let you pick up your home phone any time, etc.
