The models aren't quite distinct as the osgText::Font will be cached and automatically shared between the scene graphs, the Font manages the GlyphTexture. Each of the viewers will need it's own graphics context and thus contextID. The osgText::Font can handle this fine, but you can't go having the buffers it uses, it'll automatically reszie but this resize needs to be single threaded. There is code in osgViewer to do this for you but are you are creating multiple viewers independently it has no way too coordinate it, so you're app will need to do this.
