I updated the branch for appliance development and added a new rough draft of the json file. Tomorrow I will focus more on argument passing and networking, which will require editing the actual images.

@cbmckni - we should outline an automated image build/test and push for when code gets merged to the master branch.
Relatively easy to do in Jenkins if we want to take that route.

@mjstealey - Definitely a good idea. I will create a separate issue for discussion.
