I think this is a great idea, and listboxes/listviews are a 
perennial topic here, so the that's a great choice too.

I'd be happy to include anything anyone wants to contribute along 
these lines for PyKDE with the PyKDE distribution - anything 
from small snippets like the iterator example above up to 
generalized application frameworks. Put your name on your work
