Looks great, although I was put off when the instructions to add a server used a goo.gl URL, and then piped the output into a sudo shell...

Would be nice if it used your own domain (HTTPS is essential!) and if the script didn't require super user from the outset (or perhaps it could explain what it is going to do, and then request super user permissions)

You are right! It's temporary option. We are testing new installer, located on our domain! HTTPS will be on next week. It's the first update for next week!
