The point in the GSMA statement where they say "by constructing a large look-up table1 of approximately 2 Terabytes – this is equivalent to the amount of data contained in a 20 kilometre high pile of books" really says it all about their response.

There are certainly some things you can say about the difficulty of dealing with the physical layer here— but anyone who would liken 2TB to 20KM of books rather than say, a $170 part from a neighbourhood electronics store, 4 hours of uncompressed 24fps 1080p RGB video, or even 50 blu-ray disks isn't really someone who's view you can trust.

How high would the stack be if the books were in PDF format? I wonder if they calculated that one. ;}

High enough to get a StackOverflowException in Java. (Which doesn't say a lot) ;)

Yes, given the mindset of the paper pushers who run these cartels and "industry organisations", they've probably assigned someone to the job of printing the table out on the office printer.

(I noticed yet another consumer electronics "industry organisation" the other day - something to do with home networking and entertainment - and wondered what the motivations are for the same companies to set yet another one up for almost the same purpose as the last one, and the one before, other than to maybe give jobs to "the right people" or as part of some kind of "tax deduction" strategy.)
