Having been through a nightmare of a situation where a client demanded this (or perhaps our sales team sold the concept and painted us into a corner - that seems just as likely) and was then locked into quickly-outdated Cisco software unless they wanted to pay to redevelop the UI with every successive Cisco update, I thought I'd pose the question: with the ease of use and integration of Cisco Touch 10 / Navigator UI extensions with third-party control systems for elements outside Cisco's normal scope of control, is there a reason to develop and deploy a Crestron user interface that emulates Cisco? You may wish to consider letting Cisco drive the bus and having Crestron do what it does best and present the Cisco Touch 10 or Navigator panel as the primary user interface if this is a UC environment that centers around Cisco. These sorts of deployments have been much more successful for us and for our clients long-term than trying to emulate Cisco. Crestron emulations of Cisco do not tend to shine for very long, unless you have a client who is intent on spending their money on Crestron UI updates to keep up with Cisco's pace of development. That's my $.02, anyway.
