Thanks! Good to hear that it is something you are looking into.
Is there a difference between auth on the different editions? When viewing https://realm.io/pricing/ there are checkboxes for auth in all three editions. When I hover for more info it says, "Identify users with prebuilt mechanisms or roll your own". However, I only found it possible to use Facebook, Google or Username/Password in the DE, but you have more options in PE/EE?
