Dear Pranesh Sengupta,
Just a quick note. Ethan J Sudman is a 15 year old amateur C++ Computer
Programmer, not a professor. Based on the discussion located at the
following web site, I would guess that there is an ulterior motive behind
his interest in tectonics (Amazing what a quick search on Google will turn
up).

The irony here is that his suggestion is indeed a great one. As I have no
knowledge about the case you brought up, I can not offer any comments, but
my hope is that the question you posed brings forth ideas, comments and
more discussion from the entire group on leading-edge questions that we are
all dealing with.
Regards,
Nathan Kuhle
