Hey Juergen, come on! I know you guys are on an optimization trip at Lovely, 
but this is great information to store on an annotation. The UUID does not 
usually need to be looked up and is mainly for external world reference, such 
as feeds like Derek metioned he wanted.

The package is also an add-on. You don't need it, then do not use it. As 
further optimization, Derek mainly needs this id for a very specific set of 
content types, so I would narrow the subscriber to only give those special 
types a UUID.

Stephan
