Use radio buttons for any taxonomy so users can only select 1 term at a time
Replace the default taxonomy boxes with a custom metabox that uses radio buttons... effectively limiting each post to a single term in that taxonomy.
A plugin options page allows the user can select which taxonomies she'd like to switch to using the custom radio-button style metabox.
