"Localize" metatags based on Domain Access

Use case:

Different "country" sites managed on a single Drupal site with Domain Access. There are a lot of common nodes which are accessible on each site, but some nodes are only managed/published per domain. Content is not translated but "localized" by this division of nodes over domains representing countries/languages.

Problem:

Localized Metatags. The client wants to be able to add metatags like description and keywords in the local language per path. The idea being that:

• "Localized" nodes have their own metatags managed/viewed for that domain
• Global nodes which are visible on each country domain have "localized" metatags: meaning that on a node which is displayed on a .fr .nl and .de domain, the assigned metatag is associated with the domain and (only) managed by that domain.

I wondered if such an intricate setup is possible with Metatag. I've seen things like Metatag Domain but that module only seems to define a global metatag configuration for the entire domain. Not per node/domain.
