Lessons: aws cli is written in python on top of the botocore aws api lib and is mostly data driven off a Json spec for a reason : the pace at which aws puts out new features makes it very hard to keep up with.
dustcluster looks very interesting. I will take a deeper look into it.
I remember seen JSON spec files a while ago in boto. I couldn't find them when I tried recently. I was thinking about using the spec in my tool. Meanwhile I'm experimenting so it's not very important but I should definitely find the spec later.
edit: dustcluster is more focused on EC2 and interaction with the machines
