I just uploaded these icon packs to devel:
http://maemo.org/packages/view/plastic-icon-pack/
http://maemo.org/packages/view/pleego-icon-pack/
http://maemo.org/packages/view/humanity-icon-pack/

These are just that users can now install just the icon packs and this is also for developers who want to create their own icon packs; just get the source of any of those packs and see how the package is made and then create your own and upload to repos
