status of inventory module

Hi folks,

my clients requested stock management for their webshop. When can we expect this functionality to be publicly released?

I checked out isotope_inventory via svn and managed to install it. I got as far as creating a warehouse and adding the quantity property to the products. However, neither the product_list / reader modules nor the cart module seem to care about the available number. I'm lost here. What can I do?

I guess I could add a custom query string to the product reader and hide items that are not available at all, but what if a customer orders more than is available?

Also, how can I make sure that the number is actually reduced if someone adds items to their cart? Somehow the cart would have to be linked to a warehouse, i suppose?

Thank you for your time
