Ether Dream in python
The canonical example is here:
https://github.com/j4cbo/j4cDAC/tree/master/tools/tester
a number of projects have been based off dac.py. Lots of them use pygame.
Most of the code only seems to run on python 2.7.
On windows, python 2.7 drops frames due to some buggy network packets.
