That would be me... :)

Thanks for the info.  If nothing else, I'll be looking into the iperf
network performance tool they link to.

We were originally considering running a masquerading/netfilter box, but
we're now leaning in the direction of configuring iptables on a bridge.
Reason being we can use spanning tree to provide failover if the
filtering box breaks down.

This is possible, but requires patching a 2.4.19 kernel to hook iptable
support into the bridging code.  The nf-hipac stuff looks good, but
probably doesn't hook into bridging (yet).
