This makes total sense and it made also sense before.
I didn't want to criticize the project, because I still think it is an great idea.
It just won't work for rented webservers or v-servers, as you usually can't install the operating system there.
When you have your own server and physical access to it, this is a good thing, because it saves you time.
However, and that was my point, most people who have a server without operating system accessible, usually are quite knowledgeable in how to set up such a machine and configure everything from scratch. There is still the time saving aspect.
What I really like is the idea of the EC2 image, especially if you have to run large scale projects from time to time. You do not need a huge infrastructure, but can still have a good control over peaks.
Ideally there would be a function for the EC2 stack to scale the number of entities uses (flexible processing power) according to traffic. That would be the ideal world...
