Split forum, different domains

[amagab]

Okay, I have a forum that I'd like half of it visible on one domain and the other half visible on another domain. Same database, same users, one registration. I will have two licenses if necessary. No duplicate content.

I've seen that you can have different styles for different forums, which is a good start to what I want to achieve.

Is it possible? Is there a mod for it?

Thanks!
