I agree any charges should be upfront and one-time. Monthly fees are normally charged if there are third-party licensing fees being passed through to the end user. This may be the case with the Revues, since it involves intellectual property from multiple sources (Android OS from Google, Logitech's own IP in the firmware) and custom code written to allow the Revue to interact directly with VIP receivers. Since the main functions of the remote work either completely within the capabilities of the DVR products, or interact with social networking applications like Twitter or Facebook that would not levy any licensing fees, I would not expect any ongoing fees as part of the product cost.
