Hi Loretta,Our AMI is hosted on Amazon as an EBS AMI so it is not possible to download it in its entirety. If you plan on using it on AWS, it is publicly available so you can use it or tweak it as desired. The EBS snapshot from which this AMI is derived is also publicly available as snap-d0a071b8.
If you need to replicate the services/functionality included on this AMI outside AWS, we have a script that defines and automates the process of building the machine image using Python Fabric. The source code (with instructions on how to use it) is in the following repository:

Hope this helps,
