Trac page with SVN directory list?

Question

Say I have repository structure like:

/svn
    /Department A
        /MyProj1
        /MyProj2
        /MyProj3

I'd like to have a page on my Trac wiki which looks like:

Projects under Source Control for Department A:
 - MyProj1
 - MyProj2
 - MyProj3

Is there an existing plugin, macro, or other neat Trac trick to allow this? I tried the IncludeMacro from TracHacks, and it comes close - it can include file output from repository items, but not directory listings.

Ideally I'd love to make these listed folders come out as wiki links (thereby implying the necessity for a wiki page named after each project).
