Daniel, could you please answer this question.  I do want to make
sure that I'm not missing something.

Indeed.  Take a look at my work so far:

http://svn.gnucash.org/trac/log/gnucash/branches/gobject-engine-dev-warlord

You'll need to follow the link to the originating branch for my
first few commits.  I put the branch in the wrong place at first.
But take a look.  I required very few changes to actually get
QofInstance to use GObject directly..  I required a few more
changes for QofBook and to get the interactions to work, but once
I got those worked out I got libqof to build pretty quickly.

I still don't think it's as difficult as you think, which is why
I'm doing it myself to PROVE to you that I'm right.

I agree with Josh in reply to this idea.  I think it's a waste of
your time.  It's adding an abstraction that we just don't need.
