There is another chance to get it done... Heard of reg1 / appid? reg1 is a 
field in the cache-table, so you can query all cache sections where a 
specific id is set. There is a switch in globals, I think it was called 
appId. If you set it, that is saved to reg1. So in the frontend (or be), you 
query all pages with your appId, after you set this ID in each case you use 
that specific content.
