VoIP wants to cut the computer cord

CNET News.com: "Mark Bruk, a frequent business traveler, always packs a Plantronic headset with an ear bud and microphone so he can plug into any computer and make phone calls on the cheap.
Once he finds an Internet connection, he only needs to download a piece of software, or 'softphone,' to make the call using voice over Internet Protocol, or VoIP, technology. The software, created by his own company, takes about 30 seconds to download and, presto, he's making a call.
Of course, Bruk, chief executive of VoIP provider CounterPath Solutions, drinks his own Kool-Aid when it comes to phone technology. But he's also a cutting-edge sort: He's using broadband Net access and lightweight software to save big money on his telephone calls."
