Sounds good.
You have have a look at the JavaPluginFramework (eclipse) -based
plugin-API and the fancy scripting-support I wrote for
to get a few ideas. If nothing else then at least how pugins and
the hooks they plug into can be nicely documented in a Mediawiki. ;)

If this turns out to have the hooks I need for my code to plug into
I may even change my code to use the "real" Gnucash for the
code that saves me so much time every weekend.
(Not all plugins are public as some are so highly specific to my
  business that I cannot refactor the business-specific part into
  scripts to a generic scripting-api..)
