This functionality is already available in package managers, if we just
take care to use it.  yum, for example, supports delta RPMs.  The way
this works is LibO would publish delta RPMs that contain all the
differences from the previous release, and then the users yum package
manager would download the delta RPM, build the full RPM from it, and
install.  This approach has been in use for about a year and a half by
fedora.  I'm not sure about apt-get systems -- they probably have
something similar.  It really saves on bandwidth.
