Hi Russel, That FAQ is obviously a bit out of date. With the 2.x series of the OSG the most convinient way to embed the OSG is to use osgViewer::GraphicsWindowEmbedded. The osgviewerglut and osgviewersdl examples demonstrate this usage model.
As for RenderInfo user data, I couldn't really follow what you are doing or why. The best I can do is point you at code that I've used the RenderInfo user data for, and that the osgText::FadeText so go look at src/osgText/FadeText.cpp. Note, there isn't any application level hardwiring here - it's all created on the fly.
