This is a message for Irish. You should save the items you want to use for the ecosystem as vob first, with the option "including all textures" (have no Vue at hand right now so the words may be wrong). Then use those vobs for the ecosystem. Save the eco as material, again with the same option switched on. Then you should not need anything else than this material to give to others, it contains all necessary information to be used by others. Look at some eco materials that come with Vue for example. The objects used there are not available anywhere else. I think this is a cool option, you don't have to be worried about textures, obj originals or pathnames at all.
