I've never worked with vagrantcloud.  Who builds these boxes?  Can we verify their integrity somehow?  We often put a lot of student data in these when developing and want to be sure we're doing our best to keep it save.  Can we use the official ubuntu boxes at https://cloud-images.ubuntu.com/vagrant/ and just install puppet?
