I misunderstood you there. Stackable routes are interesting, and indeed
simple. They are miles apart from my work, and certainly not innovative. They
are interesting to this discussion, however.
In the discussion of STREAMS vs Linux networking I was not the right person to
give a simple overview. I figured that my response was more useful to John
than keeping my mouth shut. Bad judgement call, as you guys pointed out
correctly.

I definitely disagree with you here. Linux, Windows and other 'production'
environments are quite conservative. Research initiatives don't have to be,
and are therefore often more cutting edge. Compare Inferno, Legion or
Singularity. Their implementation may suck compared to linux. The ideas
embedded can form a basis for features in Linux 2.9, however. Hell, 9fs has
recently been ported.

ofcourse, because his goal was to improve upon this state-of-the-art. Mine
isn't. I have to learn how these things work, even implement some features
(such as reassembly) in order to continue with my main work. But nowhere do I
state that I am an expert on these topics.
That my kernel knowledge is not 100% perhaps disqualifies me as kernel hacker.
This says nothing about my qualifications as researcher, where other
knowledge is of more importance. Implying that I am not just inadequate at my
job, but even dishonest ("a charlatan") without knowing what I do is out of
place
