del.icio.us and flickr make a big thing of showing "related tags" when 
viewing results for a tag. The underlying data to present this should 
presumably be in term_relation. You can calculate it on the fly but it's 
DBMS intensive. So it needs calculating in background via cron or at 
save time. And yes, it could be done via hook_taxonomy.
