Marc - I think your concerns are justified, it's all very well saying they will fly at safety altitude using NVG as a navaid but they still have to get down at the other end. That is where you need your 2 crew, 3 axis autopilot, NVG compatible lighting(internal and external) and most of all a rad-alt with an audio warning. Single pilot NVG ops are not impossible but do require well trained and equipped crews in regular practice.
Frankly the extra nav assist benefit of NVG at 1000' plus is only to see other aircraft - a map and a GPS will sort the nav out.
As for IFR - the single pilot must be instrument rated and the aircraft IFR capable. As you know, you can get yourself into bad weather without realising it much easier on goggles than without so being able to IFR abort is a must.
Eventually governments must understand that to provide a night capability safely costs money and if they try to skimp on equipment and training the resulting bad press from the inevitable accidents will come back and bite them in the a**e.
