[+/-] One PDA replaces two PCs, a laptop, and three phones

Andrew Greig uses his WiFi network for Internet, television, and telephone. He cancelled his telephone line and cable TV service. Then his neighbors dropped-by, saw what Andrew had done, and they cancelled their telephone and cable TV services, too, many of them without having a wired broadband connection of their own. They get their service from Andrew, who added an inline amplifier and put a better antenna in his attic. Now most of Andrew's neighborhood is watching digital TV with full PVR capability, making unmetered VoIP telephone calls, and downloading data at prodigious rates thanks to shared bandwidth. Is this the future of home communications and entertainment? It could be, five years from now, if Andrew Greig has anything to say about it....

Somewhere in Andrew's house is a hefty Linux server running many applications, including an Asterisk Open Source VoIP software PBX.... [H]e runs a Linux thin client on a Sharp Zaurus SL-6000 Linux PDA....[which] runs applications on the server....

Walking around in his house, the Zaurus (equipped with a tri-mode communications card) is a WiFi VoIP phone running through the Asterisk PBX and connecting to the Vonage VoIP network. Walking out of his house, the Zaurus automatically converts to the local mobile phone carrier, though with a data connection that still runs back through Vonage. At Starbucks, it's a Wifi Vonage phone. At Andrew's office, it is a WiFi extension to the office Asterisk PBX AND to Andrew's home PBX. That's one PDA doing the job of two desktop PCs, a notebook PC, and three telephones.

Yeah, but what about that wireless TV? How does that work?... Link
