If you provide me example of misclassified file, I will try to find some
time to look at what need doing to fix the problem.

Using socket is not a bad idea in itself, it is just that you should not
have it as a goal, but as the consequence of the application design.

If you have a clear set of python API for your application (class
interface), just creating one class to export those interface to other
application with socket should just be trivial.

That is why I like rodrigo idea, as once you have a clean core, adding a
new interface should just be easy, whatever way you want (socket, tcp,
http, GUI, ...)

Your comment seem to indicate that you do believe that a pure python
core using twisted could cause problem with the socket idea. It should
instead help it.

I will say it again, have a real good look at twisted, understand it
fully and you will probably learn as much as a 4 years degree in
software engineering.

For me GUI mean, Graphical User Interface, the part which interract with
the user. In a MVC (Model - View - Controller), it is the View.

(it have been sometime I did not look at MVC, so excuse me if I messed
it up the part).

> or maybe you mean "skin" by gui?

If you think in term of Gnome for example, glade provide the skin/GUI,
the callbacks provide the Controller and the Model is the Database
backend. The callback should be interface to the core which link all the
components together.

Only running what is needed make sense.
