Hey @progand 
I always find it fascinating how it’s quite often the case that a few different people start looking into very similar things independently at the same time!
I don’t know if you’ve noticed the announcements yet but we have just launched the new Ember Guides app that is essentially a fully working “static” site. I’ll be jumping into some deep-dive blog posts soon to explain how every little bit of it works but we have already updated the Guides App Readme and the Contributing guide on the Guides Source with details of how to get started contributing.
If you are interested in this static-site generation side of things then we would really appreciate your help on the Guides App and you should be able to figure out how to take some of the tech and run with it on your own projects. I have already built a side project that uses the same tech as the Ember Guides called Ember Casper Template
From the top of the readme:
This project is designed to be a fully-functional, static site implementation of the official Ghost Casper Template built on EmberJS with fully working out of the box SEO friendly output. It supports being hosted on AWS S3 or any other static site hosting solution.
And all of the above also uses prember (thanks @ef4
