On a slightly more serious note, what ever eBay comes up with to replace Turbo Lister it must have the possibility for off site database storage.  No way I would trust eBay to not lose my listings (its already recently happened with images).  I have just on 10000 listings for two stores on Turbo Lister (backed up on a NAS drive) that's just too much blood sweat and tears to see vanish in a puff of ebay smoke.
