Hi Ilja,
    Yes, I agree, the best approach is using a form of Lorentzian ether
theory. I did take a quick look at your webpage - lots of math : )  Have
you considered what you believe ether to be physically? i.e. a
non-compressible or compressible fluid, or something more akin to a
Bose-Einstein condensate or superfluid, or the ether of Maxwell, or
something else? I ask this because you mention ether density and velocity,
but how ether moves and whether its density varies should be different for
some of those possibilities, so just curious where your theory stands on
that.
