And the DNS.  For redunancy freaks, having multiple interfaces that provide
routing to a lo0 alias is ideal, but to make it really work you need to force
the source address of outgoing packets to have that soft address.

This means that NFS and other UDP services that want to 
match up source address with what they are expecting (ie. what 
they just sent to) simply _work_.

Yes please, lets have it.
