Hmm, I dont know.  I suspect that #1, adding hooks into the objects
for callbacks at various stages would be relatively easy, maybe a week
or two of work to learn where to do it in the qofobject code in CVS
HEAD.  And then maybe a bit more to flush it out and make sure it's
all working.

#2 is probably going to take a LOT longer.  GnuCash just isn't set up
to have external callers.  I suspect that's a number of months worth
of work, at least.
