As discussed during the Seattle Dev Managers' meeting on 2006-01-05, the task is to change the binlog to be a [pluggable] storage engine.
Additional information for this task (from Elliot Murphy): "One of the long term goals for this is that we would be able to switch to different storage engines (like NDB) for holding the binlog at some point in the future. Making interaction with the binlog occur through a normal engine interface is one step towards that. Of course, selecting from binlog would also be nice." -- Trudy Pelzer, 2006-01-19
