I like this idea! This would make for really minimal FreeBSD-based
router/switch, which wouldn't have the bloat of FS related things.
It would have to have some userland, though, in order to manage the
configuration, routing protocols and SNMP requests.
I wonder how Cisco's are doing this, from the operating system's point of
view... When you configure the type of routing protocol on a Cisco, it
looks very similar to starting a new process (e.g. ospf router), and when
you look into memory statistics, it seems that their IOS has a notion of
processes...
