About LENR: It can be turned off on S1R, great. But has anybody used a “black photo” with the lens cap on and computed his own noise reduction with this photo ?   Is this the way to go (to get noise reduction, but only once, not in every single shot) ? Or is another procedure better ?     Did anybody try it ?  What is the best way to get this “sensor noise photo” ?

I would have thought the palaver of doing your own noise reduction with a dark frame in PS would ultimately take longer than the LENR frame when taking the photo. 

I suspect that a single 'universal' dark frame might be subject to changes anyway depending on length of exposure and sensor temperature etc, so it would not be 100% effective. 

If camera companies can't find an easier and more effective way of doing it then I doubt if any home made remedies are going to be better. The astro chaps use multiple stacked images and specialised software ...... but that is hardly applicable to normal landscape or low light photography where you want to take many different compositions. 

From what I gather the best solution is a sensor that has very low background noise levels, such as in the X1D. However, trying to squeeze more sensitivity and signal amplification out of ever smaller pixels is not a recipe for low noise.

It will not necessarily be better, and it does not need to be. But it would enable several photos in a row without missing a longer time interval between them (without using two cameras), for example if one wants to follow a certain object. People have done it before, before the cameras were able to do it automatically. So it must be possible, but the question is, is there a "best practice" of doing it ?
