Yes, it will be. While we intend for the shares through Vagrant Cloud to be free for personal use, private proxies will cost money when they're available. But we intend for Vagrant Cloud to be fully self-installable and designed it that way!

There are always alternate localhost tunneling solutions you can use if you want a private domain and don't want to pay. But if you want the `vagrant share` integration and a custom domain, we'll be charging for it.

+1 for a private Vagrant Share - like Hosted Chef versus open source Chef. A few clients I have would pay for this.
