I wanted to get feedback about whether releasing our module sounds like a good idea.
Our company has developed a module that publishes static Drupal nodes to S3 as they are saved or during a full site crawl. We've used this on a few projects where there is a need to cope with large traffic spikes (e.g. websites that support TV broadcasts) and where the content is relatively simple but there is still a need for content management. So quite niche but hopefully useful to some.
I've had a good look and can't find anything that does the same. The Boost module, which was our inspiration in some ways, didn't provide exactly what we needed - complete separation from Drupal (never hitting it) and the Boost module crawler is deprecated.
There's more detailed information here http://numiko.com/labs/2012/12/static-drupal-sites-for-high-traffic/
A future improvement could be to allow destinations for the static files other than S3 (pluggable modules).
