Hi Mike,
You wrote, in part..."Since we are just now scratching the surface of SV, I am sure 5-10 years from now we will have even BETTER solutions!"
I agree with your projection as reasonably likely*. If you consider how significantly enhanced iFly GPS has been in the last decade... all in incremental steps, that projection seems reasonable.
Seems possible that virtual vision combined with ADS-B becoming fully real, could eventually reach a point where using it for IMC landings could make the current ILS seem as outmoded as GPS has made navitagtion by VOR.

* The caveat being that our current administration doesn't break the whole ATC system with something as risky as privatizing it?
