Multi domain user publications

I am using the Domain Access module to serve multiple domains with shared user and publication database tables. I have this working; all domains have a working publication list, and publications are shown on users profile pages.

With this setup, I have the following (conflicting?) wishes:

• I want to restrict publications to specific domains.

  I can do this by setting the 'Domain access options' to publish only to certain domains.
  When I do this, a user profile shows only publications of a user in the current domain.

• I want to have the user profiles of all domains show all publications of a user.

  I can do this by setting the 'Domain access options' to publish to all domains. When I do this, the publication list of any domain contains the publications of all other domains.

How can I get the functionality that I want?
