Almost all the actual algorithms assume to be inside a QgisApplication. It's obvious, being born as QGis plugins. Anyway, I think it would be a good plus being able to run (most of) them from a CLI, given that SEXTANTE handles the layers I/O from filesystem. If I remove QtGui calls from my algorithms, they could be used from console, as far as I have an out-of-gui version of AlgorithmExecuter and QgsLayers.
What do you think about this? giovanni
