Sprint to Turn iPod Touch Into 3G Mobile Hotspot?

The Peel from Sprint, is a great example of what future accessory business looks like. There are various kinds of accessories, which morph in into the shape device and provide additional value added service. We have envisioned a similar concept where the user can add a case to iphone, and the case holds various sensors ranging from health to environment. Batteries packs are the most common and successful accessories at least on iphone segment, which eventually expand their scope to new range. The Hot-spot solution look interesting but should i kill my exiting DSL and have this an alternative or as add-on to my DSL. The later is an expensive proposition, which may work in enterprise segment but not for the regular consumers at this point.
