I don't see any particular gains however since high traffic pages (static or otherwise..) served off S3 will end up costing way more than on a shared host/dedicated server.
What would be an exact use case where this would really be important and help out ? I'm just trying to understand what need it solves and under what circumstances hosting static pages on S3 is beneficial in cost/performance.
We ended up developing both sites in django, which made it easy for them to add copy during development and see how it would actually look on the site. Once finished, we got the HTML output and sent it over for them to put up on their servers.
We were pretty happy with how it turned out, and I think django-medusa being able to automate the whole rendering to html files would be nice if we have to do it again.
Well, in that case I can see how this tool could be really handy! Thanks for the input :)
