We need to talk.

Got a DS? Got WiFi? Got friends? Then you've got a ready-to-go VoIP phone!
The DS really has still only yet to tap its hardware potential - WiFi, mic and touch screen should make for some amazing homebrew software eventually, and releases like this are still just scratching the surface. iPhone? Screw that. You've got a touch screen, WiFi and voice-recognizing doodad already! C'mon Nintendo (or h4X0r fellas), unleash this puppy!
