ownCloud is a free software alternative to some proprietary web services that includes music streaming, file management which supports sharing, calendar, contacts and more:

ownCloud offers the ease-of-use of Dropbox and box.net with a more secure, transparently managed offering. As an open source project ownCloud 3 offers innovative features, a flexible architecture and no vendor lock in.

- Built-in cloud text editor that supports 35 programming languages for syntax highlighting, keyboard shortcuts support, automatic indent and outdent, unstructured / user code folding and live syntax checker (for JavaScript, Coffee and CSS). Editing more advanced file types like .doc and .odt is planned for a future release:

ownCloud text editor

Application Store: support for installing third party applications and addons through a central repository, directly from the ownCloud interface

new calendar interface

various calendar and contacts improvements

A new "external" application that lets you integrate external applications (like an external webmail interface for instance) into the ownCloud interface

Unfortunately, this release doesn't bring encryption, a desktop sync client or versioning/recovery yet, features which many consider extremely important, but fortunately, all of these features are top priority so hopefully we'll see all of them in a future ownCloud release.
