A $49.99 Samsung CDMA femtocell with a $30 / month service for a household ($15 for individuals) including unlimited VoIP for all calls generated within the gizmo's reach (supposedly 5,000 square feet). In Denver and Indy right now and nationwide by the end of Dubya's second term, that's Sprint AIRAVE.
All Sprint customers can use your AIRAVE (3 at a time) but need to subscribe to the service to enjoy unlimited calls.
And oh. YOU provide the broadband access by cable or DSL.
The F-VNO (Femtocell VNO) is born.
