As you have probably seen in the home page, there is an intention to integrate EasyNAS with OwnCloud.

OwnCloud is one of the best cloud sharing application for you home use.  I have been testing OwnCloud features with easynas volume manager to gain from both worlds.   So in the next easynas version OwnCloud will be a feature in EasyNAS.   You could install the data on any volume and even change it online.
