I have been playing with Plasma Mobile on my laptop from a LiveUSB and I really like the interface ideas behind it. I have been thinking recently about building a new desktop which would act as a home theater/smart TV.

There is an app available for Ubuntu and Windows called Splashtop http://www.splashtop.com/ which allows streaming of your desktop to your phone for remote control, would something like this be possible using Plasma Mobile? I think that would make for a great user experience and an extra usage for your system.
