I'm considering rebuilding a drupal site in wordpress and am still wrapping my head around the differences between the systems - particularly cck/fields and custom content types and the different ways to use taxonomy.
I would like to know if two custom content types can share one custom taxonomy. In drupal I can limit the posting of a particular content type to a group of users and then that posting can have taxonomy that is only shared with one or more other content types (but not all types).
Leaving the user aspect out which appears possible with role scoper, can you do this with wordpress? I've only seen custom content type with custom taxonomy but no way to share a given taxonomy between 2 or more custom content types without recreating it in two places or enabling it globally through categories/tags...
