OK, I'm experimenting with this kind of integration right now. Not with 
Slide but with Daisy. Take a look at the Daisy plugin in whiteboard.

Currently, the location of the repository is encoded in request 
parameters. This is *not* good.

The problem with this approach is that a) it is difficult to write the 
hrefs b) it is impossible to build a static site because the request 
parameter '?' is converted to an '_' in the filename ('?' is not legal 
in a filename)

The solution to this problem is the locationmap work. This allows you to 
map request patterns to a location. For example:

<match pattern="docs/**">
   <location href="http://127.0.0.1:8080/slide/xdocs/{1}"/>
</match>

For more information see http://issues.cocoondev.org/browse/FOR-200

I'm currently experimenting with the locationmap code, I have it working 
"to an extent". But have not yet managed to get it to work at the 
generation stage (through lack of time rather than a problem with the 
code, I think). I will attach a patch against the current SVN tree to 
the above issue that will enable the location map if you would like to 
experiment with it. It would be great to have someone working with me on 
this, you with Slide, me with Daisy (and Thorsten is looking at Lenya 
integration).

I prefer the locationmap method to the forrest.properties method because 
it means that we can integrate content from multiple repository 
locations and multiple repository types within the same site.

Cool.

With the Daisy integration (and I assume Lenya) this will be possible. 
Those systems provide full workflow control. I would be concerned about 
duplicating their effort here in Forrest. What would be good though is 
for us all to agree on a standard repository plugin that could be 
configured to work with various different repository tools.

Again, with Lenya and Daisy integration they also provide navigation 
editing. The Daisy plugin does not currently use the navigation from the 
Daisy repository but it is a simple case to make that happen.
