Absolutely. If you end up allowing components to manage/message each other, code can get very message and be incredibly difficult to evolve afterwards. I'm guessing this was one of the ideas behind my gut feelings against JMX as a Kernel.
My suggestion is to allow for heirarchical containment models (not as uncommon
as you might think) and only allow containers to manage components. That will
make things alot simpler to develop and debug, as well as enforce a predictable
security model.
Definitely. Anything that allows a cleaner separation of the elements in a system will make it easier to manage. Containers should really be the only things that manage components, not the other way around.
