This is fine if one can accept the level of insecurity within a site.  WHat
about sites that don't necessarily look like an edge router but rather a cloud
with multiple entry points.  You then have the possibility of a host not
knowing which source address to select.

Source address selection has been a much overlooked issue in the debate since
most of the descussion seems to me to be focused on delivery.
