Latency.  Specifically I want muli-threaded replication so I can better take
advantage of mutli-core slaves.  I'm willing to assume the "risk" associated
with saying "yes, I'm sure that each of these logical dbs are logically
separate, and no statements will cross them."

Cache consistency and invalidation.  Google had a nice hack for stuffing
extra info into the binlog so that other tools could pick up the changes and
export them into non-MySQL systems.
