Server-based (hosted) documentation and user comments (DocBook?)

[Crimmin, Peter]

Can anyone recommend technologies to do the following:

*	Hosted documentation, available on the internet as a web
service. 

*	Each doc topic allows users to add comments. (e.g. "Here's a
better example to do this task...") 

*	Management tools to moderate user comments, and to handle
documentation updates (retaining the comments). 

*	Authoring tools to produce said documentation. 


The open source community exploits these technologies. How do they do
it? I have an inkling for a solution: FrameMaker>DocBook>ePublisher?
 
Thanks for your ideas
