Superpy distributes Python programs across a cluster of machines or across multiple processors on a single machine. Superpy lets you send tasks to remote servers or to the same machine via XML RPC call. It has a GUI to launch, monitor, and kill remote tasks. It works on both Linux and Windows and can run as a Windows service with submitted jobs running as the service user or the submitting user via password authentication.
pymds is a simple, authoritative-only DNS server that has a simple module system for customizing how name resolution happens. The main motivation for starting this project was to create a simple system for building smarter DNS servers, capable of geography awareness, geographic load balancing, application aware load balancing, etc. Current modules implement standard behavior of using a file based DB to answer queries and to provide simple round-robin load-balancing across several servers by altering the order that IP addresses are returned.
Surnia can check an OWL ontology/knowledge base for inconsistency and entailments. It is implemented as a wrapper around first-order theorem prover (OTTER, for now at least). Unlike Hoolet (which turns the OWL into FOL), Surnia just turns the OWL into triples and mixes in axioms.
SPIN_py is a Python module that wraps the SP SGML parser. It does not follow SAX, nor DSSL, but it performs a similar task. It has code to build (and pretty-print) trees from C++ or from Python, and it has an interesting object model, with virtual C++ objects, based on PyObject_HEAD.
