Well, an extension would then need to hook into TCEmain and watch for 
its records to run by as they get created or changed. When this happes 
the extension needs to take care of marking certain parts of the cache 
as "dirty". This should all be very simple for extension developers by 
using an API - otherwise if it isn't easy, they won't use it...
