I have read through the article and I am left with a question:
In what way will the Dragonfly BSD be a hybrid of monolithic and 
microkernel model?
Although this question seems to be answered in the text, it would be 
nice to have a black-and-white list, explanation, with a number of 
diagrams explaining the exact intended architecture of the kernel.
Which services will stay in the kernel, which will be moved over to the 
user space? Can we see a more detailed elaboration on the context 
switching and message passing between the two spaces?
Personally I find the lack of proper development and design 
documentation a big pitfall for many of the free/opensource projects.
