Since the gelman project is developed by python, I need a python wrapper for AWS:
PyAmazon is a XML-Object mapping for Amazon Web Service, however, the interface is obsolete and the current maintainer, Michael Josephson does not show any interest to upgrade it.
pyamazon4 seems to address this problem, but so far it is mere a place holder.
OK, I would wrap my sleeves and start this dirty work.
UPDATE: Accepted by Sf.net, Here is the new project PyAWS.
