I found http://owncloud.org after looking through the http://tagspaces.org site.

I really can't wait to install them and see if they are the personal content management systems that I've been looking for for years.

They both can also be installed on Window/Linux/Mac/Android/iOS/Web (on private server, nice interfaces, PHP based I think).

Anyone know of similar web-based (but self-hosted) software like this that might be life-changing?
