Oh, I see now.  So you would want something along the lines of a 
pointer/reference-like Lockable that has a constructor which can take a 
reference (or maybe a shared_ptr) to an already existing mutex.

Is there some way to make it possible to use boost::bind for this?  So you 
could bind together a Lockable and a function returns a reference to the 
object you're interested in, and then use it later to create a 
scoped_lock/lock_acquirer?
