If you are able to save an OAR, you might be able to box up your stuff and save a copy of it that way.
If your vendor filters the OAR export, you won't be able to save some items, of course.
Another option is XML exports, which allow you to save things one item at a time. The Imprudence viewer is most commonly used to export and import objects and their textures: http://wiki.kokuaviewer.org/wi...
