Hi,

Your proposal is almost perfect. You have been able to implement a POC 
and generate the documentation using the Boost environment tools. You 
seem to master the problem domain.

Concerning the project proposal, I would like to see the following 
points more elaborated:
* Why do you think that value semantic would be better?
* How would you specify the queue as a policy parameter?
* Do you plan to make the thread pool configurable?
* Do you plan to port it to C++98 compilers?
* What your performance tests will measure? Do you plan to compare 
different implementations? Value-semantics versus shared semantics? 
Different queues? Different thread pools?

Concerning the millstones, I would prefer a week based schedule and that 
as far as possible each iteration includes something adding value with 
the code the tests and the documentation. Maybe enumerating the use 
cases by priority would help.
* 1-1 transformations
* 1-N transformations
* N-M transformations
* parallel segments
* make use of thread pools
* queue configuration

On each of these use cases maybe you could list the classes that you 
will need to work on (roughly). Indication for each one which use case 
will be a must/should/nice to have would help you to make a better plan. 
Indicating also which performance test could be done at each step would 
also be useful. Note that a plan is there to help you not constraint you.

Let me know if you want I help you on this.

Best,
Vicente
