Roland Schulz and some others were working on this and I believe
have it mostly complete. I think the remaining problem was in
loading a Python widget from an app with Python already running
(using QWidgetFactory?) - the widget tries to load the Python
interpreter itself, but gets the running version of Python and
runs into thread state problems.
There is a library (libpythonize) which is common to all of the
plugin type stuff (panel applets, KControl, QtDesigner, etc).
It's basically just a simple wrapper around libpython.a, but in
some cases it runs into problems that haven't been fixed yet.
Hopefully Roland's still on the list and can provide you more
detail (and code?)
