good! The idea was to move all cache-related functions to this class (if 
possible) and substitute it with wrappers.
Followed by good documentation so devs know how they can proper use them.
Also possible are some usable pi_base-wrappers to allow easy usage (eg 
$this->pi_clearPageCache($pid) )

very good hint. It doesn't makes sense to use an integer (who knows if this 
is a unique). So using varchar is the best way.
So you can use the extkey ore even more advanced tags (eg using keywords 
from pages)
