First of all, there is no reason to CC a question to three lists. That is just a big waste of bandwidth. If fault tolerance of network interfaces and links is your big concern, there are already ways of doing that. Simply use a new alias IP bound to lo0 and then advertise that via a routing protocol to your router or routers. If an interface dies, routing updates can't be made from it, so the border router(s) won't send traffic through it anymore. This is easy to do, I just never found it worthwhile since NICs might very well the most reliable component you can buy these days (at least for Intel Pro100+s anyway). I've never had a NIC fail in a server yet. Many people are interested in load-balancing traffic over multiple interfaces. There is an equal-cost routing patch that can add this.
