From what I see, the domain is something you should already have in your control, and that's good. Otherwise, it would be really hard to maintain such a project. The system should be good at handling Hive tasks; adding support for domains would increase complexity and introduce extra security concerns.

For those interested in trying it, I can help with the domain and server setup. The best part is that anyone with very basic admin skills (even if they aren't related to Hive) would be able to assist in setting this up.
