Feature Request: Import/Export of layouts

I would like to see an option for importing/exporting a layout as a package (zipped?) containing the screen design, timings, and necessary media. This would give the following (and probably more) benefits:

 - providing/using 3rd party designers becomes easier without giving remote access to the server
 - coordinating with corporate marketing/graphics departments for creating and testing fully developed layouts/presentations and media becomes much simpler
 - moving layouts from one system to another becomes possible (such as using/re-using presentations from trade-shows)
 - provides a vehicle for backing up and restoring layouts with appropriate media
