Actually he is looking for _outbound_ loadbalancing, not inbound.
If you have three interfaces, and a default route pointing out fxp0,
won't all responses that are not local go via this interface anyway?
(e.g. NetBSD doesn't always reply via the ingress interface)
Depending on the topology you can "load balance" your routing info
across the three interfaces. So each remote subnet can be routed
out of a different nic.
