Does Colin Bruce have the answer to the size of the multiverse?

I bought his book "Schrodinger's Rabbits" yesterday, and have been 
skipping around through it.  Some of you may recall that I have 
questioned if there is any theoretical way we could estimate the size of 
the multiverse if it is not a continuum.   I had suggested the size may 
be related to the number of possible alternative outcomes down to the 
Planck scale (which seemed logical enough to me anyway).

Bruce introduces what I considered a very interesting concept, which may 
be old news given the book came out last year, but I do not recall 
seeing it discussed.  He suggests the holographic principle may provide 
the answer.  If the amount of information a region of space can contain 
is proportional to surface area,  might  the "volume" contain 
subinformation of multiverse processes?  To quote Bruce: "Perhaps a cube 
10^100 Planck units on a side can indeed store about 10^300 bits of 
subinformation or multiverse information, but this capacity has to be 
divided between 10^100 world processes, giving only 10^200 bits of 
stable "real" information capacity to each."

Bruce admits this is a speculative idea, but provides explanations as to 
how it is an interpretation that explains several aspects of our 
universe.  I will go into more detail about this if anyone cares to hear.

I must admit I'm biased here toward liking the idea because this 
directly addresses several key questions I have had about the structure 
of the multiverse, including the relevance of the holographic principle 
to the MWI.  Anyone care to weigh in on the prospects for Bruce's idea?
