A beginners MPI question :

I want to use MPI to port a blackboard based system with many
(dynamically created) process. Some of these processes may define and
use private blackboards for local communitcation. Processes are packaged
as UNIX processes.

The question is: can such a system be built with the concepts of groups,
context and communicator as defined in MPI-1 ? What would be the
underlying assumptions ? Or would it be better to wait for MPI-2 which
explicitly supports the notion of dynamic process creation ?

The book "Using MPI" by Gropp, et.al. does give an example of a
blackboard system, but its not clear if processes can be created
dynamically in that system. 

Thanks for any advice or pointers to similar apporaches.

Cheers,
