Comment 3 for bug 1119412

Better solution, after some email discussion with Matthew Wedgwood: make it possible to specify a location to download the gui, and make it possible to specify a single archive (or no archive?) that will be used to obtain all deb dependencies.

For the first, I imagine adding charm functionality to support a directory URI from which to download releases. This could default to a CDN location. If no version number is specified but a directory URI was available, the charm would look on launchpad for the newest version and then download the release (named juju-gui-RELEASE.tgz) in the directory. If a version number were specified, the charm would look in the directory URI for juju-gui-RELEASE.tgz without contacting Launchpad.
