* Information storage:
Hints of a limit to how much information can be stored in a spacetime
region come from the holographic bound.
* Information propagation:
For massless fields, whereas energy propagates strictly only on the lightcone,
it has been shown, at least in 2D, that information can travel also inside
the future lightcone of the source.
