Hi, I just wrote a short blog about a new EC2 interface that Ian Duffy and Darren Brogan have been working on for course work:
http://buildacloud.org/blog/321-new-ec2-interface-to-cloudstack.html Once they get their grade for this project we should all be able to send pull requests and if we want merge it in CloudStack code (to be discussed) I want to bring this to dev@ as this might be a way to offer an improved EC2 interface and deprecate the current awsapi. Removing awsapi might simplify packaging for 4.5 Cheers, -Sebastien
