Albert, A future release of Mathematica will support the ability to name arbitrary directories as locations for paclet content, so that shared paclet repositories can be created and managed by an administrator and made available to all users. If you _really_ want to do this right now, contact me directly and I will show you how to do it in the current release. It's not yet a polished, documented feature. Todd Gayley Wolfram Research
