Hi, I am using ownCloud ( <a href="https://owncloud.com/" rel="nofollow">https://owncloud.com/</a> ) I just was pointed at this post: <a href="https://owncloud.com/blog/lightning-fast-innovation-gives-ownclouds-latest-community-release-greater-flexibility-ease-of-use" rel="nofollow">https://owncloud.com/blog/lightning-fast-innovation-gives-ownclouds-latest-community-release-greater-flexibility-ease-of-use</a> in the new version, there is an API for developer. I am not sure if this API will fulfill the needs for a storage system for Roll20, but for those who has their own owncloud installation, it would be a nice feature. I know, this is probably a huge work load and I don't expect you to include that API. I just wanted to point you to a posible soloution.
