Multiple processes can run against the same repository files, Berkeley DB 
supports that just fine. So, if you're not running Chandler and want to make 
your data available somehow, another process for that is still possible. But 
this does not imply that Chandler has to go through that same process to 
access the repository, it can do that by accessing the repository files 
directly via the same Berkeley DB APIs.
