Groupware for Small Consulting Organizations?

vrmlguy asks: "I've worked for several small consulting organizations over the past few years, and have discovered an unmet need. Every place I've worked has developed lots of code (usually scripts) that rarely gets reused except by the person who wrote it. Management always talks about 'knowledge management systems', but nothing ever gets off the ground. Does anyone know of something that works? I've looked at the CMS Info and TECFA Portals Pointers web sites, but haven't found much that seems to meet my needs. What I think that I need is something similar to sourceforge, but without the bells and whistles. BSCW looks like the closest fit, but I've got a few concerns about its licensing. The ideal solution would let me control any code that I upload, and search other peoples' code for stuff I can download and modify for my own use. CVS is overkill, since I expect that people will rarely check things back in that they've downloaded. Ease of use is important, since people always think it's easier to write from scratch than to search for things to reuse. Security is paramount, since there will be a lot of code that, for various contractual reasons, we don't want to share with anyone. Does anyone know of a great project that I may have missed?"
