Choosing the best source address is a definite plus. Sometimes. Other
times, I don't _want_ any "best" source address, I want the address I'm
always using... the only reason I have to add a second address is that the
_other_ guys don't understand multiple networks and I have to do some
routing there by hand.

But do we need the added complexity for the IP router to search not a
single list (interfaces) for possible local matches, but a list of chains,
many of which will have only one link?
