Code similarities are probably quite easy to see, as before writing  
Envers I looked through Hibernate, Validator and Search code :).
The startup code is indeed similar, but then it diverges (as these are  
two librarie for different purposes). When versioning relations, I  
have to change the original mapping to include the revision number  
etc, so that complicates things.

As far as I remember, the autoregistration is done by checking if the  
listener classes (their names are simply written there as String-s)  
can be loaded by the current class loader. So adding a similar feature  
for Envers would require changing Hibernate code. But maybe that  
changed :). That's really not a question for me.
