Let me start by saying that I picked this message out of the few posted in
response to my original message due to the part Abigail picked at.

The comment about the stats going down was more of a comment then it was a
wish. As far as the stats go, they are useful, but shouldn't be a reason
people don't participate in a certain project. Also, with the dcypher.net,
keep in mind that they just started a distributed system, so they don't
have the problems d.net has with stats. I find it amazing that d.net can
even provide the stats they do after seeing the processing power required
to churn out stats on my personal proxy machine.

By what I understand, CSC uses some extra layers of encryption to try to
make it secure. By us cracking it in the quickest amount of time, we prove
that the extra layer doesn't help as much as simply moving to a higher

I had a feeling that this would come back at me. The reason I am not
making a case about RC5-64 is due to the fact that the RC5 contest is not
time limited. If we crack RC5 one or five years down the road, the reward
is the same. With CSC, if we can't beat the deadline, the reward is lost,
and all the work done has no benefit. Even if we cracked CSC one day after
the deadline, the publicity wouldn't be as great, and the awareness of the
weakness of CSC wouldn't be as high. Once D.net starts OGR, I won't
personally care what the majority of people run. When OGR starts, it
introduces a new goal for D.net participants to pick from. But for now,
all the contests D.net has run are all encryption contests, so the force
should be put behind the one that is time limited. The last DES contest
has a very short time limit, and would have been possible to loose out
on. If the top one hundred teams has said "Stats are important, so we have
to keep cracking RC5 instead of DES", we might have missed the deadline.
