So is this a way that I can use Calibre on my PC to tag things, convert them, etc. Then have it dump them to my dropbox folder and all my devices would automatically get updated with the new books in the library?
That's what I'm trying to accomplish since I have my phone, my wife's phone, and our tablet. I just have to install Dropsync on each of the devices?
Can I then use pretty much any reader as long as it points to the right folder?
Very interesting idea. I was going to look at Moon Reader's dropbox sync but there's not a ton of info on exactly how it works.
