Paid. Features are customized to the client so I'm not too sure what will be in it for the public. You will be able to have it so people can buy points, admin can manually add points. You can spend on avatar selection or the more expensive custom avatar. Coloured names. Services such as ad removal and open up sections of the website which will use the criteria section. You will have criteria that says something like "User has purchased service: [] ad removal" etc. Then you can use usergroup promotions or other means to change the website. Ad removal can be a usergroup or if my ad management mod can simply use the ads criteria settings. Transaction log, think paypal but prettier. Gifting points or items.
That's just off the top of my head. I don't see much demand for this so it will probably be a while before it comes out, I need to sort out my site first.
