Create a file sharing Sugar Extension for the Journal, based on Web Services [1]. Use MegaShare as the back-end service [2].

As with other extensions for the Journal, this one must allow to "Copy to" journal entries directly to the MegaShare service. Once the file is uploaded, the file URL must be available as a tag in the details view.

This extension behavior is identical to the Pastebin [3] extension, except that this one copy all kind of files, not only text based.
