execnet enables zero-install ad-hoc instantiation of local or remote Python processes. It establishes channels for basic data communication. Data Serialization is independent from Pickle and is tested between Python2.4, 2.5, 2.6, 3.1 and Jython interpreters.
execnet-1.0.0 (compared to 1.0.0b3) has bug fixes, new tested examples and introduces execnet.Group for managing a dynamic bunch of hosts. See the improved docs
and below the changelog. I am set to improve and develop execnet further and thus am very interested in feedback and suggestions.
