@_emboss_ Communicating n inputs 0, 00, 000, ... costs O(n^2). Storing the same inputs in a crit-bit tree costs O(n^2). What's the question?

@_emboss_ Another nitpick: crit-bit trees guarantee performance linear in the input size; worst case is a few dozen cycles per byte.

@hashbreaker But if input size is unbounded, ever longer inputs perform poorly or don't they? Maybe we can discuss this in Hamburg :)
