Having previously written the App Python and deployed on Windows and Mac using PySide it was relatively simple to translate the code to use PyQt with the object of deploying it on other platforms (esp for iPad).

Once there were all in place using pyqtdeploy was not too bad.

If not why do the pyqtdeploy instructions talk about the multi platform directory structure - is this just so that the project file can be moved to different platforms without being changed?

Yes.

pyqtdeploy doesn't handle building anything, it pushes that out ot qmake. So cross-compiling support (out of the box) is whatever Qt supports.
