Maybe I should put a disclaimer in the README, but I originally created that box for development purposes. It should most definitely *not* be used for production. That's why the firewall is essentially turned off in the last step so I can get to MySQL, SSH, *whatever* easily from my local machine as I'm developing.
As Brad said, their fork has a lot of great updates that I want to roll into this one but I can't do a regular pull request b/c I wanted my box to keep using Apache and MySQL. I've created a few tickets on the repo with references to the relevant files in their repo to bring some of the good stuff Brad and the folks at Ortus did in their fork back to my repo. Anyone who cares to pick those up can feel free to fork the repo and submit pull requests back.
Glad to see it's been useful to some folks.
