You would store and edit your assets in Guvnor, then build your package which exposes the .pkg file via http. At this point you can do whatever you want, retrieve the pkg file(s) from guvnor via simple http and place them wherever you might need. Your client applications can use KnowlegeAgent to periodically pull the "latest" pkg from either Guvnor or a location on your file system.
Hope this helps.
