My favorite interesting packaging choice is TeX Live in Fedora 18 [1]. There are about 4500 texlive-* packages (out of around 35000 binary packages in Fedora total). The packagers split up the packages based on upstream metadata.
They also include the meta packages [1] so you don't have to install every package individually if disk space is not an issue.
