Synchronizing Application State Using Virtual Dom Trees

We will all soon have numerous computing devices we use every day interchangeably. Liquid software, a concept where software is allowed to flow from one computer to another, is a programming framework that aims at simplifying the development and use of such multi-device software. The existing research has discovered three major architecture challenges for liquid software: (1) adaptation of the user interface to different devices, (2) availability of the relevant data in all devices, and (3) transfer of the application state. This paper addresses the last challenge and differs from the earlier work by concentrating in application state that is in the DOM tree, a key element in today's Web applications.
