And as far as I know, it's working just fine, thank you.
Although you can say no more, if you wish...

We aren't bothering to keep many of our stats. All we want is
a solution.

Hmm...we actually have around 5000 machines, since the ones
behind firewalls don't get reported. Did you notice that you
have three times as many machines as us, and are struggling to
keep up in key rate? If we had 15000 machines running our
clients, we'd probably be done. I think you need to spend more
time looking into optimized clients and less time looking at

Pretty impressive, considering that you're running at 300% of
our total machine count and 600% of our keyserver count. Spent
your $10,000 yet?

Undoubtedly--it'l be nice to have some competition... :)
