Taxonomize taxonomy terms?

Terms and posts are both WP Objects, but different ones.

They are stored in different database tables, so…
… they don’t have unique IDs (term and post can have same ID), so…
… they’re IDs cannot be both used as foreign key in database, so…
… I don’t think it’s possible (well, maybe it is, but it won’t be as easy as you think it is).
