Jon,

As the UWB standard evolves, IMHO the need for device interworking will also evolve as a wireless data hierarchy starts to materialize. UWB interworking with Wi-Fi, and Wi-Fi with WiMAX, etc.

Beyond the hierarchy issue, perhaps we will see more peer-level interworking or primary and fall-back network routing, as we're currently witnessing with planned GSM/GPDS and Wi-Fi multi-band and muli-mode PDA devices.
