QWS can be used with either of OpenGL-ES profiles subject to the
availability of Qt graphics driver plugin for your OpenGL Es
This plugin, in most cases, is specific to the OpenGLES
implementation. For example, Qt comes with a driver plugin for OMAP3
OpenGL ES implementation.
For that you have to configure Qt with "-opengl es X" option and build
that driver plugin.

Yes.. as per trolls Lighthouse is the future of Qt windowing systems.
