Hi Ben,
we also pump data from cameras into the GPU. To enable PBOs is simple:
// make image
osg::ref_ptr<osg::Image> myim = new osg::Image();
// attach pbo
myim->setPixelBufferObject(new osg::PixelBufferObject(myim.get()));
// point im to data, avoid copying (mod format here for your app)
myim->setImage(ImageFormat_[i].getWidth(),
ImageFormat_[i].getHeight(),
1, 1,
GL_LUMINANCE, GL_UNSIGNED_BYTE,
my_data_pointer,
osg::Image::NO_DELETE);
// assign to texture
mytexture->setImage(myim.get());
Now, when the data update, just call myim->dirty() and all should
update. You can also call setImage again.

Thanks Jason.
I've used FBOs before for render-to-texture. I'll take a look at PBOs.

You might try using PBOs (pixel buffer objects). I think the
osgscreencapture example shows them in action.
