Jacques Exelrud forwarded the following from Peter Trei:

<cough> Well, it's a nice theory, but where are the dual-core clients?
Not a sniff of them so far and we're getting awfully close to the
starting gun. A comment: beyond 5pm GMT us Europeans tend to leave work
and we'll lose a chunk of overnight cracking time... except for the
devotees willing to wait up for the clients' release.

Could the Powers That Be give us some idea of what's going on, please? I
notice that the DES II client and proxy pages are up; but at the moment
they're only mirrors of the corresponding RC5 pages.

Hmm... comments? I don't think that the ideological goals are as strong
with DES II as they are with RC5; we all already know that DES is weak.
But DES II makes a nice show of strength for us; it's a useful
morale-booster; and yes, the prizes could help bolster the d.net
infrastructure nicely...
