Very nice!

Users of other OSes won't even believe it is this easy!  Have
you considered writing this up for a publication or blogging
about it?  This sort of "joy of programming with plan9"
stories need to be known more widely.

What's really missing is a whole book on hands on OS hacking
along the lines of the Art of Electronics or SICP (Structure
and Interpretation of Computer Programs).  And with a kit of
h/w & i/o devices so that you can build some widgets and
give'em a real OS!
