Thanks, setAI. This is a nice, readable paper. The list of references in it is an excellent resource, too.
From page 4:
"If instead the observer focuses on his perceptions, he will make, in his mind, automatically the two limits [itex]N \rightarrow \infty[/itex] and [itex]A \rightarrow 0[/itex]"
where [itex]A[/itex] is the area of a cell of the cosmological horizon and the limit on [itex]N[/itex] means that, classically, we should expect no cosmological constant, even though the number [itex]10^{120}[/itex] is significant for physics at the Planck scale.
