I don't know about subversion, but I'm guessing the origin of the baton
concept came from the running race [1], where an item is passed from runner
to runner. Historically, this baton would have some information on (or in)
it, that needed to get to its destination quickly.

Not to be confused with baton twirling, though. [2]. :-)
