Intranet packages?

[Dan Coutu]

I have a client running on Red Hat Linux 5 that has a home grown gnarly 
intranet that needs to be replaced with something that's a lot more 
useful and easier to navigate and maintain. I've been investigating 
different open source and commercial packages that provide an 
out-of-the-box type of intranet and thought I'd ask here about people's 
experiences, recommendations, and ideas.

What has to be covered:

- role-based access control to different areas
- logins should be able to hook into the system logins so that adding an 
account to the system also adds to the intranet
- document management that allows upload/download of various files (word 
processing, spreadsheets, pdf, images, etc.)
- integrated search capability
- shared discussion areas
- action tracking (trouble tickets that are sometimes for todo lists 
instead)
- must run in house on the Linux server

This is not exactly groupware and doesn't quite fit a number of other 
packages already out there either. Packages investigated so far are:

Intranet Connections - too Microsofty by using Access
Instant Intranet Builder - MS only
Intranet Dashboard - MS only
Vialect Intranet - could be promising - Linux with PostgreSQL or Oracle
Hot Office - a hosted solution
First Class - Mac and Windows only
Teamware Office - Windows and Solaris only
Punch Webgroups - a hosted solution
Traction Teampage - could be promising - Mac/Windows/Linux
