If do, this would mean that: 1) You would not be able to use FreeBSD for hubs; someone has to be up first, and whoever it is would go immediately back down. 2) You would not be able to come back up automatically in a noisy environment; you would need human intervention. 3) Similar to #1, you would not be able to use a reversing cable to connect two machines directly without a hub.
