It seems to me that Bohmian beables are obviously required.
1) fact is that we live in a classical macroscopic world where the fundamental observable is Maxwell's local classical electromagnetic field tensor F
obeying in Cartan form notation
F = dA
dF = 0
d*F = *J
* = Hodge dual
All our information about other fermion matter fields comes indirectly via F and also A if you include the Bohm-Aharonov quantum effect.
Therefore, the basic classical observable is the F electromagnetic field.
As Basil Hiley explains this beable F is an infinite-dimensional field configuration on a spacelike or lightlike surface in which each spacetime event is a "dimension". It has a super Q and photons are not localized like massive fermions are. If, instead of the continuum, we use a voxelated 3D + 1 world crystal lattice (Kleinert) then the hologram principle tells us that the lattice spacing is not the Planck length Lp, but rather it is L where
L^3 = Lp^2A^1/2
A = area - entropy of the horizon screen Seth pixelated computer

is N = A/4Lp^2 = A^3/2/L^3 ~ 10^52/10^-70 ~ 10^122 in our actual causal diamond pictured here
Showing Apast and A future with 3D volumes of both retarded history and advanced destiny influence on the 3D lightlike slices. I think Susskind's student Raphael Buosso at UC Berkeley has worked this all out mathematically though perhaps not with the advanced Wheeler-Feynman -Cramer-Aharonov effect?
Note the change in Heisenberg's uncertainty principle which according to Susskind et-al is
&x ~ h/&p + Lp^2&p/h
However, I think it may really be
&x ~ h/&p + L^2&p/h
Lp = 10^-35 meters
A^1/2 = 10^26 meters
L^3 ~ 10^-7010^26 = 10^-44 meters^3
L ~ 10^-15 meter ~ 1 fermi ~ 1 Gev

Hawking's black body radiation is a horizon surface effect
T ~ A^-1/2
I predict a second high temperature horizon thickness Hawking radiation of temperature
T' ~ (LcA^1/2)^-1/2
(LcA^1/2) is the proper length quantum thickness of the Horizon as a "stretched membrane" (Kip Thorne)
Therefore, the stretched membrane is a very efficient Carnot limited heat engine with
(Work outpu/Heat input ) < 1 - (Lc/A^1'2)^1/2 ---> 0 as A^1/2 ---> Lp (Planck black hole)
Lc is the formal UV cutoff
Now there may be a spectrum of such cutoff's. Sinziana Paduroiu's astrophysicist colleagues in Paris suggest that Susskind's cut off of Lp corresponds to Hawking gravity wave black body radiation.
Note that for precision cosmology (LpA^1/2)^1/2 ~ (10^-3510^26)^1/2 ~ (10^-9)^1/2 ~ 10^-3 meters ~ 10^11 Hz corresponding to the observed dark energy density. However, it is easily shown that this must come from our future horizon as a retro-causal back-from-the-future "destiny" (Aharonov) effect.

Thanks Jack, I'll look at these. But to the extent that you have to adduce a Bohmian picture to support your claim, I can't buy it, because I don't think the 'beable' approach is correct. I don't agree that there are 'beables'.
