You mention Trial below and I think using it is both the easies and
the most correct way to test code using Deferreds.
You simply return your Deferred from your test case and Trial waits on
it to determine if the test passed or failed.
I like this tutorial for Trial: http://ln-s.net/24:F
VIFF (Virtual Ideal Functionality Framework) brings easy and efficient
SMPC (Secure Multi-Party Computation) to Python. See: http://viff.dk/.
