[Bf-cycles] Monte Carlo variance denoising

i stumbled across IMO a great technique to denoise trough MC variance. It is pretty simple. Its from Innobright.
Now i don’t know the legalities, but it looks pretty simple, some AOVs and a MC variance filter. Could be implemented in GPL ?
Also would this be only a node necessarily (still cool) or could this be a renderer feature (more elegant) getting it straight of the renderer ? Lets say, shooting 2x 128samples and variance filter them in GPU RAM without saving 2 images. Like i see it, it is pretty powerful.
Your thoughts on this guys?

Many thanks,
