And the effect of DDOS attacks? Sure, maybe your pipe will fill up long
before you start maxing out connections to the 400. But even a 400 isn't
going to like 500,000 IP connection requests per second... and don't
forget, they're br0ken requests, so the TCP handshake is only half
complete so the 400 needs to wait to see if finish. If I'm on a separate
machine then I'm good (machine is down, but backend isn't), if I'm on
one machine/card, well...

You still have at least one firewall between your i and the internet, yes?

Shouldn't it take care of that kind of nastyness?
