I developed hack to synchronize Kobo Touch with Google Drive. It uses open source Linux client called grive (https://github.com/Grive/grive
). When the eReader is online files are automatically synchronized. You can find download link and installation instructions from https://github.com/softapalvelin/kobo-grive-sync
I wrote about it in http://blog.softapalvelin.com/2013/0...h-ereader.html
