multiple domains question!

Hi
Thanks for this module, its really a good idea, i have couple of site in french one for france using .fr one for belgique using .be i just want to have a different website with .be that display a section with belgique news and some cck content type and views.. Could this module do that will be a conflict with seo as it will be duplicate content, same content for different domains, i can correct that with allow disallow etc, i don't want to hack drupal core as this module need some patch, i never do patch, if anyone please can provide me with the patched file so i can copy to ftp, any tutorial available or exemple to see this module in action? I think its a good idea to add such a tool to drupal 6 as we have multilang website, multiple site, multiple domains with same database, its just perfect
