[Hipsec] Memory-bound puzzles in BEX

[Tobias Heer <[e-mail]>]

Hi everyone, 

RFC5201 states that memory bound puzzles should be reconsidered for future versions of the document. The exact text is here:

NOTE: The protocol developers explicitly considered whether
a memory bound function should be used for the puzzle
instead of a CPU-bound function.  The decision was not to
use memory-bound functions.  At the time of the decision, the
idea of memory-bound functions was relatively new and their
IPR status were unknown.  Once there is more experience
about memory-bound functions and once their IPR status is
better known, it may be reasonable to reconsider this
decision.

I am asking the list if the time for reconsideration has come. Should we delve deeper into non CPU-bound puzzles for RFC5201-bis or should we keep this note for future revisions.
Is there anyone with a background on memory-bound puzzles interested in having them in RFC5201-bis?

Best regards, 

Tobias
