Sorry about the delay, we are fresh off a release and somewhat out of breath.

Here are my unsorted and quick observations about 
http://www.tech.gfusa.org/images/MOAP/GnuCashArcht.png.  Someone else correct 
me if I a wrong:

-There is no XML between the GUI and the engine
-To my knowledge none of the HBCI code is in the engine.
-There is an abstraction level, the backend, between the engine and SQL, XML, 
RPC, etc.

We really should create one big logical diagram of GnuCash in an easy to 
maintain format.  A perhaps even more usefull diagram would be a diagram of 
Gnucash's hi level data model.  So many things to do, too little time...

From http://www.tech.gfusa.org/images/MOAP/GnuCashArcht+MOAP.png I don't 
understand exactly where we fit into your model.  On that diagram (I probably 
don't understand properly) you have both your own GUI and your own datastore.  
What is it you want to leverage GnuCash for?  The GUI, the data model, the 
data store?  It's not very clear to me.

I presume what us want is to leverage the engine (and thus the data model.  Is 
that so?
