Hi, Tom.

I think I can safely say we will never attempt AES.  We're in this to
show what distributed computing can achieve.  In the case of RC5-56
and -64, we were showing that the encryption restrictions of the U.S.
Government (and others) were inappropriate.  In the case of AES,
nobody is questioning that the encryption is strong enough, because
it obviously is.

RC5 and CSC were both contests organized by their creators, with a
prize.  Nobody I know is offering a prize for cracking a secret AES
message.

OGR has a useful outcome for the scientific community.  We will have
achieved something by taking on this task.

AES has no prize money, no benefit for completion, and no reasonable
chance of finishing before the heat death of the universe.  (Think
about this:  If you were to try cracking AES by hand, the odds of
finding a correct answer before you die are essentially the same as
the odds for d.net finding it, because in both cases the number we
would try is so small in comparison to the keyspace.)  Taking on AES
would not show what distributed computing can achieve, because we
would never achieve anything.
