Robin,
I had the same original "displacement" concept until recently
and I think it is roughly equivalent to the "up shifted" term Scott and Thomas
introduced me to. The issue with the "displacement" concept is it carries with
it an image of a vacant portion of space where the displaced wavelength used
to reside. While my relativistic theory doesn't exactly match either concept
the "up shifted" concept Thomas Prevenslik first introduced me to comes from a
thermal dynamic perspective of Casimir effect - I used to consider this the
"other" camp for Casimir theory vs. the "displacement" camp that I was more
comfortable with - Thomas comes at this from a perspective of thermal dynamics
and will argue the plates are not "pushed" together and that ether doesn't need
to exist to explain the effect, he explains the effect as an imbalance created
by "up shifting" causing the plates to self attract. Although my
"relativistic" concept now represents a new 3rd option/camp I chose to refer
to the "up shifting" version as the alternative because it already deals with
what I consider a misconception of there being a "vacancy" - the energy
summation is still reduced because energy content reduces with wavelength until
some cutoff frequency beyond which it is meaningless to integrate, therefore an
up shifted spectrum will also sum to a lower energy total. For a while I just
went with the idea that the vacancy got filled in with shorter wavelengths but
the "up shifted" concept already handles that issue plus it is an easier
transition to the "relativistic" concept because it already has the same
remote perspective of faster wavelengths inside the cavity... the only thing it
lacked was my position that the wavelengths would appear unchanged to a local
observer in the cavity... which as I have said previously is more in keeping
with the changes in energy density, anomalous increases in C transition time
thru the cavity as measured externally and
Claims of variation of radioactive decay rates.

As I understand it, they are not normally upshifted. They are excluded
altogether, because they are too long to fit in the cavity. It's precisely
because they are excluded that they press on the outside, but not on the inside
walls of the cavity, hence producing a pressure that pushes the walls together.
Only the wavelengths greater than the cavity dimensions are responsible for
this, and since these represent but a minute fraction of the total, the force is
very small, until the walls get very close together. That's because as they
approach one another, the excluded wavelengths get shorter and shorter,
representing an ever increasing amount of vacuum energy.
