For now, you should be able to run 'nodeq -l ip port vnum' to get
a list of content-hash keys stored on a given node if the node
is running.

You can also use 'dbdump -e dir' where dir is the raw database directory
managed by adbd, such as "5d6d6572c251f87de5ba440caad57d62d69195f4.c". 
(This is just a wrapper we provide that is similar to the db_dump that
should come with your Berkeley DB installation.) 

Neither of these methods are particular efficient and will basically
read the entire contents of the database off of disk.
