Since you're checking out Bonded Sender, can you request a zone transfer or rsync from these guys too so we can check their data?
Note that the Bonded Sender status of a sender (are they or aren't they) is incorporated into the IADB data. The same for Habeas status, and whether they publish SPF records, among many other things (the complete list of information one can glean from an IADB lookup is available here: http://www.isipp.com/iadbcodes.php)
As Jeff notes, you can sign up to query here: http://iadb.isipp.com/iadb_query_sign_up.php
If you have any questions, or suggestions, please feel free to contact me personally.
