Hi Simon, I would like to see osgWidget be generalized to work in 3D, I haven't had the change yet to dive in and use osgWidget actively yet, so haven't got grips with the code base yet, it's something I have planned, but it'll have to wait to after 2.10 is out, which takes us into August.
In the meantime perhaps you could try rendering the GUI to a texture rather than a HUD, and then apply this texture to a QUAD that you position in the 3D scene. You'd need to remap the mouse coordinates into from the 3D coords into the coords of the GUI texture using a technique such as I used for the osgWidget::PdfReader, VncClient and Brower classes, these all utilize the osgViewer::InteractiveImageHandler to do the reprojection of coordinates.
