I don't really see why it would be better for crowdfunding than the Asset exchange... or digital good store if you prefer a stable price.
Because you can set a block height so if your target crowdfunding Nxt goal isn't reached, the MS coin isn't created and everyone gets their money back (called Reservable). With Assets, people buy the Assets and their money is gone regardless if the target is reached.
We also need to check how certain features will get used out in the wild.
