I replied to your support ticket regarding the same topic. For your convenience, I am duplicating the answer here too; perhaps it can be beneficial to other users.
in general, packaging an app with phonegap is not so hard, and doing so would also make sense in certain cases. In fact, Kendo UI Mobile utilizes the SPA router internally for navigation. Should you go with a separate UI, you can still share the code base on the model/datasource level - both apps may consume the same data endpoints using the Kendo UI DataSource component.
