The docs could use some help.  In particular, an intro/tutorial type of 
page.  Or just a little example program that shows how a full active 
object can be built would definitely help.  The active object could 
contain a few public active_function objects corresponding to the 
"servant" object's public methods, and a private shared_ptr<scheduler> 
(used by all the active_functions), and a private shared_ptr<servant> to 
hold the servant object.  

You might want to wait a few days though, as I'm currently in the process 
of making a few changes to the API.  I've switched to using the slot class 
from thread_safe_signals for tracking, instead of boost::function + 
shared_ptr<void>.  I'm going to split a reference-counted "promise" class 
out of the future class as suggested recently on this list, which is 
responsible for setting the values that futures see.  I'm also adding 
support for forwarding exceptions from an active_function's underlying 
function to the returned future based on Peter Dimov's exception_ptr.
