I have a client who has been using WebOffice (from WebEx) for a variety of tasks within their small organization. The problem is that they only really need a small subset of the features WebOffice provides (Contact list, Database, and Document Storage).
They've asked me to develop a website focused on these three features with the rationalization that this should be more cost-effective, since they currently aren't using many of the features of WebOffice they pay for.
What are some open-source alternatives that I could implement for them? Sharepoint sounds like it would be too bloated and Google Apps may not be as collaborative as they would like.
