Heh, what do you mean "started working yet"?  All those docs in
that folder didn't get left by the Tooth Fairy! :)

WRT actual software, we built a working version of the event channel
which has no CMF dependencies at all.  The remaining effort is to
wire up the event producers (factories, content objects, etc.) and
the subscribers (the catalog, first off).  We are also trying hard
to measure the performance impact, as such a tool could suck up a
*lot* of cycles if we aren't careful.

We will likely move the event channel product into the CMF module
sometime in the next few weeks, with the "plumbing work" to follow
very quickly (assuming no disasters emerge in the performance
testing).
