I can't follow your argumentation anymore. How do the following statements fit 

"Please provide an example of what this would look like. I really need to
understand how this will simplify anything."


"And I don't see much point in learning how trunk works until it stabilizes."

... so what do you want? Daniel and I spend our spare time on improving trunk 
and this takes time as nobody is paying us directly for this because we do it in 
our spare time. We have a clear goal and we communicated it dozens of times to 
the list and added all open tasks to JIRA.
If this is too slow or insufficent for your needs, you need to get involved by 
getting your hands dirty. You're complaining that things in trunk don't work as 
they should? Hey, that's your chance! I don't think that it's rocket science to 
improve things.

                                      - o -

*If* you had took the time to learn a bit more about the architecture that 
Daniel is proposing, you would learn that our work on OSGi isn't affecting the 
non-OSGi-Cocoon in any way. Look at the current way of setting up Cocoon:

"[...] The CocoonServlet creates a CoreUtil which creates a CocoonBeanFactory 
which in turn is used to get the Cocoon component, which in turn delegates most 
of it job to the SitemapLanguage which also is a component that is managed by 
the CocoonBeanFactory. A fun exercise for the interested is to try to figure out 
how and where the Cocoon component is configured and created. [...]"

Daniel's proposal was about making this process simpler and this has *nothing* 
to do with OSGi. Daniel and I believe that OSGi is the way to go but this 
doesn't necessarily mean that everything we do is OSGi-related. As we had to 
understand Cocoon internals in greater detail, we started to think more and more 
about how to simplify things, and believe me, there is room for improvment as 
the core of Cocoon has grown and got too complicated over the years.
