IPod Touch Capable of VoIP Calls

The new iPod Touch is fully equipped to work as a VoIP phone, according to Cult of Mac.
On the new Nano and Classic, the mic is solely for recording audio. But the Touch has Wi-Fi. While Apple explicitly forbids VoIP applications from accessing the 3G and EDGE networks on the iPhone, it appears that VoIP calls over Wi-Fi are fine. All it needs is somebody to write an application and put it in the App Store.
