How sustainable?  A key issue that needs to be raised is funding. Currently the VDP is funded by a range of corporate partners - including Microsoft and Google. However, for the project to be sustainable in the long-run investment is required from a wider range of bodies, and further partnerships need to be formed with the public sector. The government needs to be included as a funder and supporter. The neglect, and exclusion, of the government within discussion on health projects - such as VDP - only acts to remove their responsibility and obligation to tackle the social dilemma. Healthcare is the responsibility of government, not the NGOs and private firms that are providing VDP.
