MPI is newer, but I'm not sure how widley used it is compared to other technologies today. Further more, it's more a definition and API to transmitting data just as DOM and XML are... Or so I understand it.

Spread, as I've seen it, does synchronization of messages on top of communicating them, which is great to talk about.

Maybe you can discuss the various patterns used as well involved in such a system. There are many distributed programming texts about. Maybe implement something ad hoc demonstrating the use of priority queues, mutex locking and the likes?
