title: Open source alternative to WebEx WebOffice?
body: <p>I have a client who has been using <a href="http://www.weboffice.com" rel="nofollow noreferrer">WebOffice</a> (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).  </p>
  
  <p>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.</p>
  
  <p>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.</p>
