Especially with Quagga's RIB+protocolRIB design. Five times 130MB of RAM ain't nice. > the daemons are separate.

There is no difference between a FreeBSD box and a "router" per you definition, see Juniper. The only thing they've got is a hardware FIB and forwarding plane. I don't want to run Cisco et al. because I can't change anything other than what the IOS cli gives me. I'm not satisfied. I can't run my own experimental routing protocols on it. I can't fix any of their (plenty) bugs. Nono, you want to use FreeBSD as router instead of Cisco, Juniper or all the others. -- Andre
