I will be interested as to how such a speculation can be built upon using the data re backgrund radiation...

I think that to understand what these guys are talking about, you must first understand what the cosmic microwave back ground is telling you.
1. 99.9% of the photons in the universe dont come from stars etc. They come from the CMB. If our eyes were sensitive to these wavelengths, this would be apparent.
2. The CMB is the relic of the Big Bang and therefore contains information of the big bang at the very instant it occurred. This information could not have been altered in any way.
3. The average temperature is 2.726 degrees Kelvin and because it is an average, there must be highs and lows.
4. So you get what is called dipoles, one hot and one cold spot. Then you get two hot and two cold spotscalled a quadrupole. Then threes hot and three cold called an octupole.This continues on etc.
5. The temperature variations of these multipoles is called the amplitude of the CMB.
6. The amplitude measurement of the first few multipoles have been done and its expected that the amplitudes of 10,000 multipoles will be measured. Lots of computing power required here.
7. This will result in 10,000 unique numbers describing the CMB. Each number could contain 10 bits of information resulting in 100,000 bits of information describing the CMB.
8. This could conceivably hold a message from the big bang and what happening before, during and just after the big bang.
9. What this message would be is anyones guess. It could say that this is how the universe is built or "Kilroy was here"
