You're doing about what we'd suggest, with the exception of that base URL. You 
should be able to simply load qrc:/qmls/start.qml and then any paths inside 
the QML (like relative image paths) should use the qrc path automatically.

We've thought about it, but would like to hear about how it goes from someone 
actually doing it :) .
