On my debian 2.0 I have a program apt-get which can do this, beside
others.
I give it the ftp, http or directory where to look for packages. Then I
give:

apt-get update

to get the info about the available packages. Then

apt-get upgrade

or 

apt-get dist-upgrade

to upgrade (download if necessary, also)  ONLY the installed packages.

Works only with Debian .deb files (on Debian), I think, not with RH .rpm
:).
