Yes, most here are armchair engineers, though quite a few actual engineers around, so you never know. But the embarassing point is: the billion dollar companies currently also don't seem to have an idea about the possible solution :p. I am pretty optimistic that they will come up with a reasonable plan soon, but there is a nonzero chance that someone here will come up with a good idea. Sometimes it quite helps to be at a distance.
