Ahh ok, that explains why I've never seen that before.

I'm all for free, except when you're technically paying for it with licensing/etc.

I was totally serious about the $50-100 boxes being better than HAProxy, they're monumentally better at the basics. Where they don't do so hot is with SSL acceleration, but considering how fast AES-NI is, I don't bother doing that with loadbalancers anymore. Also fully HA and you don't have to deal with source/dest NAT issues if you're using DSR.
