Bonobo controls are not discouraged as far as I know. Just part of the
API must be rewritten because of some incompatibilities with the new
gtk+ menus ans toolbars.
Having a Bonobo control in ghemical seems a good idea. But I don't thing
that ghemical itself should use it. My idea is that we should have some
widget containing all ghemical views and embed them either in the main
app or in a bonobo control. I think such a control could be embedded in
gchempaint.
About the interoperability with gchempaint, the situation is that the
next development version (0.5.2) plane for the end of this month will
export a molecule to a ghemical file (in /tmp) and execute ghemical with
the file (there is a contextual menu item which appears when ghemical is
present). The result is not perfect but things work.

I'll have more time this year, so if I can help with ghemical, tell me.
I don't know many things about molecular modeling (it was not available
to the undergraduate students when I was one, only mainframe computers
existed and time was much too expensive), but i can help with auto*,
user interface and bonobo. Note also that the bonobo component is
deactivated in gnumeric at the moment, but there are plans to
reimplement it hopefully for 1.6 (1.4 should be shipped in october and
1.6 next year).
