Confirm Address Change During Order Process

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/2a31179a5f2ad511#

Hello,

in order process, on billing and shipping pages, user can manage his
addresses: select from drop down, add a new one, or directly enter an
address.
I encounter the same thing as we have I admin pages: there's absolutely no
confirmation upon changes (another address selected, address validated...)

Is there an easy way to use a tag to say "Change have been made"?
