Slightly different from the other issue.

We have products which may or may not be in stock, but can be ordered at short notice, therefore require that an 'out of stock' item can be added to basket, AND checked out. (Full discrimination is carried out elsewhere in code to check if an out of stock product can be ordered)

An administrative interface to check / not check stock would be useful. I'm off to hack uc_multi_stock_order, and while not ideal, will fix this problem.
