Interesting.  The packaged_task part seems to have a lot of overlap with 
promise.  Wouldn't you get the same functionality from a boost::function<R 
()> plus a promise as you get from packaged_task?  Maybe I'm just not fully 
grasping its purpose.

Also, have you considered supporting implicit conversions between future<U> 
and future<V> where there is an implict conversion between U and V?  My 
libpoet library does that, and it's helpful for passing futures between 
active object functors that return futures and accept them as arguments.

Are you planning to submit your future library to boost?  Is boost still used 
as a testing ground for standard proposals?  I suppose at this point, getting 
a futures proposal into C++0x might be the fastest way to get it into boost 
in any case.
