This is a fair statement. Any projects whose formats signifigantly
deviate from the RC5/DES model will basically have to wait until V3
is a reality.

Now, Peter, this isn't fair.
First and foremost, it's always been a given that a bulk of
the DES-II monies will be given to charity, just as we did for
RC5-56. This reduces, somewhat, its effect as a motivating factor
for us. Secondly, you and I spoke on the telephone last week and
I expressed my sincere hope that DES-II would fall before you were
to speak this Friday at the RSA conference. I think we both understand
the impact that would have and the positive spin you'd be able to use
in your presentation. Not a single person within the distributed.net
DES key once it's identified. The sooner DES-II falls, the better.
If we find the key today, you'll know about it today, guaranteed.
Our sights are aimed at a number of targets, one of which is the RSA-155.
There is no chance that we would intentionally sabotage our performance
in the DES-II challenge for a minor gain in subsequent DES challenges when
there are so many other opportunities for us outside of the DES Challenge
