The last comment is correct - Vagrantpress was initially my crack at an environment to do some simple theme development without a lot of the overhead of setting up other environments. Now that I do production support and server provisioning for "many" WordPress sites, I'm going to be incorporating some of that knowledge into the Vagrantpress product: my day to day needs are not development focused, but rather in automating the provisioning / maintenance of many Wordpress installs. I hope you'll see some of those changes in the project in the coming weeks.
