Great news!  With a few changes and some hacks/workarounds, I've got 
some basic things working:

f = chebfun(@(x) sin(x), [-2, 6])
f = chebfun('sin(x)', [-5, 5])
f(pi)
g = f + 1

In particular, the "chebfunpref" problems I had last time I looked at 
this are resolved!  Likely by jwe's changes to persistent variables and 
subfunction scope if I had to guess.

Anyway, I've updated the wiki above with a link [3] to my changes, so 
those would be a good place to start.  I've downgraded the project from 
"hard" to "medium" because now at least one can start without touching 
Octave internals at all.
