Heh. Its far better to be doing this and keep folks interested (it *is*
interesting trying to see how long this will take..).

And given the rate at which we 'accelerated' during DES-II, we are more
than likely to recruit a lot more folks as we gain more publicity. We're
going through RC5-64 a lot faster than before DES-II.. perhaps DES-III
will have a similar beneficial effect. :)
