Clever :-) Glad to see another solution out there!
Myelf -- I've migrated almost all personal and small projects over to a self-hosted dokku instance. All of the static sites run this buildpack: https://github.com/dokku/buildpack-nginx
This has been a real timesaver as dealing with S3 static sites was just a pain. Added bonus is I have more granular control of nginx (if I want it)
