But I am thinking of mains like the following:

if __name__ == "__main__":
	import sys

	app = QtGui.QApplication(sys.argv)

	mw = BeverageMainWindow()
	mw.resize(800, 600)
	mw.show()
	sys.exit(app.exec_())

This is a prototypical __main__ which I'd like to be able to %run from IPython 
as well as from the commandline.  If I want to reuse code, I'll import the 
file and reuse BeverageMainWindow, but not the __main__ code.

Maybe then those people put too much code into __main__?

Have a nice day,
