This also applies to the substantial computer resources and technology as
well.

Something on TLC got me thinking about this even before I read this
message.  The NSA has a problem in that, except maybe for quantum
cryptography, they no longer have an advantage of kind, merely of degree,
and the market is narrowing that gap daily.  Before, only they had the
resources to do something like the machine NCR built to crack enigma
messages, and could build many one-of-a-kind machines to do individual
cracking.  They still can, but it isn't efficient to do so today.  They
can build 1000 custom ASICs, but they will be more expensive than 10,000
off-the-shelf CPU chips - they can't do engineering any better or cheaper
than Intel or DEC, and they don't have millions of customers to spread the
fixed costs over.

When a camcorder is more complex than most weapons systems, but is
available at the local mall, and when I can buy SMP servers from an 800
number, I have the same thing the NSA has, only smaller.  But the NSA is
still a finite size (given the earlier posts about terawatts), and I can
link my computer with thousands or millions of others.

DEScrack was only done on a relatively few computers.  If a really big
prize was offered (In this lotto, you just run this screen saver which
uses less bandwidth than pointcast... The chinese radio lottery via the
internet), you could get almost every computer into the act.  As
technology goes forward, any advantage of largess will be overcome by
greater numbers of small systems - at some point the large college
campuses will have more cpu cycles than the NSA because students bring the
latest technology with them.  Unless the NSA is radically different, the
concept of putting a SMP system on everyone's desk (upgrading it every few
years) and linking them isn't going to go over as well as getting 100 new
cray supercomputers.
