Dear Matti,
I apologize for the delay... First I would like to ask if you are
familiar with John G. Cramer's ideas?

I believe that this idea offers a good scenario to understand possible

Can it be proven that such retrograde "classical signals" can not be
used to create a perpetual motion machine of the second kind?

It should be obvious that the possibility of retrograde classical
signals and typical assumptions of SR would allow for the construction
of a Maxwell's Demon type device that uses the information about the
"future states" of the device to extract energy from a heat reservoir
without the generation of entropy! It would be like a >100% efficient
heat pump!

The word "real" is problematic to me! It must be remembered that the
global view of a superluminal communication network of such a
four-dimensional society would be equivalent to a preferred inertial
frame in contradiction to SR, but we may be able to avoid this by using
an operator type definition of time, e.g. instead of a single absolute
inertial frame for all members of the society, we use an operator
relation that considers the energy/time uncertainty relationship. This
implies that we would need to figure out how to define energy and time
from the point of view of the individuals.
I have been thinking in terms of periodic gossiping in graph theory
(used to model the communications of nodes in a network of computational
systems) to consider this situation. Perhaps connecting the notions of
gossiping with spin networks might be fruitful... :-)

I am not familiar with this concept. :-(

Can a space of such pulses be defined? What would be its inner product?

This looks a lot like Cramer's proposal! What I have been thinking is
that space-times structures are constructed by this type of
q-jump/communication! The light-cones are defined by the solutions to
optimization/ minimization computations that are dual to thermodynamic
entropy extremizations. This idea follows along similar lines as
Frieden's EFI principle...

That looks like Sagan's Contact scenario! :-)

That is very true! But isn't it neat how sci-fi anticipates physics...

I will be trying to get copies of these papers...

This is similar to Feynman's absorber theory?

The Z^0 field is the electroweak field?

This last aspect is very interesting! Can we think of superconduction
situations in these terms? Does it give us a way to think of anyons and
supersymmetry? (http://risc.ftj.agh.edu.pl/~bozon/plde/listof.html)

This is very interesting! It could very well be that gravity does not
actually "propagate" at all! This would explain the negative results of
gravity wave detectors...
