GVoice does not turn your touchpad into a WiFi phone. Nearly all other features of google voice are supported,as far as I am aware, to some degree.
I would love to hear you guys input as to what would make for a great gvoice app. Obviously the phone thing would be nice, but it uses an entirely different service that uses a library that is notoriously difficult to get working on a native compiler let alone on a cross compiler with limited support libraries.
but I would love to hear suggestions for other gvoice related features!
