Hmmm.. see Spring.

If I want to add interceptors, the kernel/container will have to somehow add
a chain before/after calling a method. I thought the best place for it lies
on the Handlers. I might be wrong, of course.

That's something my grandma won't like to see :-)

Good diagram.

That's the first time I browse into Dojo's code. Damn, its good!

IMHO what Pico achieved is good, but I don't like the way it achieve it. To
me a container should be more ... hmmm.. inteligent to assemble itself with
no - or little - hints from the user. 

There are space for containers implementation yet, with different flavors.
Status quo from us will not relate to our promisse of "past and future of
IoC containers" :-)
