Hey, I just published an egg, binary, and source distribution to PyPI: http://pypi.python.org/pypi/avro/1.3.1. There are likely lots of things to improve about the process. Please add your comments to https://issues.apache.org/jira/browse/AVRO-482, and I'll be sure to sort them out. Once we have a stable process, I'll update http://wiki.apache.org/hadoop/Avro/HowToRelease.
Lastly, if you know of another ASF project which is publishing release artifacts to PyPI, please point me in that direction, and I'll try to follow their lead. Thanks, Jeff
