The basic currency module is now installed, which means you can 'buy' and 'sell' objects (or copies of them) for $0, i.e. for free. No real or game currency is planned, however. The advantage is that you can easily transfer ownership of items at will, whereas previously you could only allow people to take copies of objects. You can also sell just the contents as a folder. Transaction history now appears on the website, although it is superfluous and may be removed.
