Yes, the $99 license is available with any hosting purchase, even month to month. And you are more than welcome to install it yourself.
Obviously, that means that someone could just purchase the cheapest hosting option for a month and then host it elsewhere to save $20, but that's a lot of hassle for that amount so we haven't written in any stipulations against doing so. But if it becomes a pattern then obviously we will because that's not the intent of the discount.
