On the main page of distributed.net we can read
"distributed.net's computing power has grown to
become equivalent to that of more than 160000 PII 266Mhz computers
working 24 hours a day, 7 days a week, 365 days a year!"
I doubt an organization could really build something A LOT stronger than
this, able to crack a 64 bits encryption in a year or so ??
