[Qt-interest] Running Qt for Embedded Linux Applications

[Bill King]

We used to do similar in qtopia, which was using the qt embedded system.
We'd have QPE application which was the QWSServer, and the shell that
launched the other applications. It provided the homescreen, the
launcher menu, documents menu, etc.
