DVC members have been known to either rent their points out for a year when they know they're not going, or just sell their membership outright if they know they're not going to be at WDW as often as they originally thought, or if they need money for any other reason.
However, I'm pretty sure the moderators on this board frown on anyone using the forum to arrange or offer to buy sell or especially rent points, because if any sort of agreement went south that was started here, someone might claim they are somehow responsible and liable. There are other places you can find online that arrange point rentals or re-sales.
