I don't think there's any way to get notified of moves when InternalMove is used. > Would it help if I switched to QListView and implemented a model?

You can stay with a QListWidget if you want, but the mechanisms used to handle dragging and dropping will be a bit different to those you would use with QListView (where you would delegate most of this to the model). The draganddrop/puzzle example provided with PyQt uses a QListWidget to display a collection of puzzle pieces that can be dropped inside or outside the list, though it's not exactly the most user friendly interface you could imagine. The itemviews/puzzle example is more or less the same, but uses QListView instead of QListWidget. It implements support for drag and drop in a custom model, which is based on QAbstractListModel to make it as simple as possible. Strangely, the piece movement is quite a bit more intuitive than in the other example.
