At some point, our coming commercial model will be "bundles", where we won't sell Xen Orchestra "alone" anymore (ie we'll group both XCP-ng and XO into a single simple offer).. XOSTOR will be an option for a bundle.
For a home lab use, you will be able to use it without paying anything (and without support obviously) by just installing it yourself manually via the CLI 🙂 No CLI feature restriction, and it's fine as long as you don't break the moral contract 😉
