I think binary logging is the wrong word to use. As far as I can tell it's not binary he means, but database logging. Storing things in a database sounds far less scary than binary.
At best it's a NUL separated database structure where the fields are not compressed, which IS greppable just use \x00 in your regexp. At worst he might mean BER, which is an ASN.1 data encoding structure.
