- Set up the necessary structures to completely seperate the virtual
  domain information and the real user information, such that each user
  can have a list of virtual domains assigned to it.  This structure
  will specify:
  - a domain prefix
  - a directory
  In this way, the virtualdomains will contain:
    domain.org:username-prefix
  And the domain listing with list
    prefix:subdirectory
  Each domain will have a completely independant user directory and
  password table.
