MVDs

When a new MVD wishes to join the system there should be a network wide vote by VOW token holders, where anyone can put forward a proposed MVD address, the network votes and if successful automatically hooks in the new MVD associated with a particular Vcurrency contract. Any merchant should be able to choose any MVD for initial setup and should have the ability to switch between MVDs

Since MVDs are essentially performing oracle services, reporting on fiat transactions and allowing merchant signup (and therefore VSC issuance) they should have a VOW stake to register with the network and be challengeable.

Deregistration should be enactable by the MVD themselves as long as they are not under challenge.
