So, this is a Xen VPS (Amazon uses Xen as far as I remeber) with a MySQL 5.6 database, with a custom storage engine that stores data in some Dynamo-based storage. Any code could access it via MySQL protocol (bindings to libmysqlclient.so). Fine.
I trust your best intention, but even Dropbox was dismissed on HN as user-friendly rsync.
We will see it shortly.)
