create relationship between posts from one category and posts from another category

Question

What I'm trying to do is adding in a post admin page a meta box, dynamically listing all posts from another category in the for of a check box list.

This way I can create relations between a post and other posts belonging to a different category.

Any tips will be greatly appreciated.

I'm not certain what you're asking, but maybe Scribu's Posts 2 Posts plugin will help you.
