I'm in the process of expanding the asset usage and would like to solicit some advice from the community. The current code that has been contributed by Hans is rather restricted to rental on items where inventory isn't easily expanded (e.g. rooms, seats on a plane, etc). My need is for products where inventory is easily grown, (e.g. televisions, home furniture, etc). The major difference is that you can essentially backorder the rental items that I'm needing. I was wondering if it would be better to A)rename Hans's ASSET_USAGE to LMT_ASSET_USAGE (limited asset usage) with parent ASSET_USAGE and name mine INV_ASSET_USAGE (inventory asset usage or something in that line of thought) for a quick and dirty implementation. Or B)to rewrite Hans's contributions to take notice of Product.requireInventory
