I probably am stretching it, but at the cost of making a hard cold
point. Acres of computers means nothing. Get specific. Acres of quad
core xen processors with 32GB of RAM each, 1600Mhz FSBUS, etc, etc, etc
means much more to me. It's the generalizations and uncertainty that get
to me. Speculation is for children. I'm a computer scientist: I want
facts and logistical data.

Also, as you mentioned, many projects are taking advantage of distributed
computing spanning the globe. I'm a member of,
where I'm spending my CPU brute forcing RC5-72 keys. Take a look at the
stats. We're probably running in the neighborhood of 30 Pf/s, and
yet, it's going to take us close to 1,000 years to successfully test
every key in the keyspace. Of course, we'll probably hit the key long
before that point, but it shows the strength of the RC5-72, and the amount
of resources needed to brute force it. Now sick my 1024/1792/2048 GPG
key after the same method, and would be long after the heat death of
the universe before you could say you sucessfully tested every key. What
about the NSA? Think they can do it within my lifetime? Or even my
seventh-great grandkids? Doubt it. Maybe if quantum computing comes
along. Even then, I'm still skeptical.

However, I am never questioning that they are taking advantage of the
brightest minds, the sharpest methods, the most powerful hardware, and
endless supplies of money. But c'mon, we have to keep our head in the
clouds. They're human, not gods.

I have to ask, though: have you seen a government datacenter? What about
one that spanned acres? :)
