I understand you are saying gambling, sex, etc... fuels demand, but right now it might not be enough
DVC has more than enough projects in the works.
For example the DVC advertising network.
If someone could clone the DGC marketplace for DVC this would be absolutely awesome: http://dgcmarket.com/index.php?
DVC has such a strong community I don't see it dying (or relying on dodgy gambling sites) anytime soon.
