For the first time, today I've installed Sharepoint om my server...
The idea under this choice is to have a reserved area on my site (based on Sharepoint Services) where to share documents and files with co-workers or customers around the world. Sharepoint is really a good product, easily customizable and ready to work soon.
The results are good... now I've a reserved area (http://sharepoint.demiliani.com) where I can have a shared Contact list and a shared document repository. Nice! 
UPDATE: As requested, here the screenshots of my Sharepoint installation (thumbnails, click on the image to view):
