Right now Mist and Graphite are the only way to access your project files and we don't plan to offer FTP or WebDAV access at the moment, although we can open up a web service API to allow programmatic exporting of a project (currently this can only be achieved through interactively logging in to Mist or Graphite).
If the web service bit interests you, please suggest it on our Feedback Portal
and we'll enter it into our backlog if other clients show interest as well.
