This blog and the GSoC project finished a long time ago.
To conclude with 2010 hindsight
- the project was completed and a featureful wizard was the result
- a python printer setup program created for Ubuntu won out over my wizard as it was a superset of the features. It was a complete printer management tool
So, what I learned is: streamed XML parsing, GUI vs. business logic separation, Qt.
Lots of fun and fond memories of late-night coding - farewell.
