I've investigating applications with documents, discussions and calendars for a medium sized marketing support intranet.

The goals for XYZ Corp are: a) To get their franchisees and dealers making use of existing documents more. b) to create marketing opportunities by inviting communication between dealers, franchisees and head office.

There's so much stuff out there that solves these problems in various ways. Thought it might be helpful to create a list of promising options.

• Community Server - Commercial, ASP.NET, $10K per CPU
• Cyn.in - Open Source, Python/Plone
• LifeRay - Open Source, Java
• Drupal - Open Source, PHP
• SharePoint - Commerical, $50 per month
• Alfresco - Open Source
• uPortal - Java
• JetSpeed 2 - Open Source, Java, Features...
• Exo - Open Source
• Google Apps - Free

Now to start the evaluations....
