IP layer can not select a destination address, though it can make
a suggestion to the upper layers.

Transport layer can not select a source address at all unless we
are doing QoS routing.

Ohira-san may be confused, because a scalable implementation of
QoS routing (designed by me and others) is running around him.

But, for most of you, it is extremely special.
