pyCA is a project to create Certification Authority in Python. It will generate a CA certificate hierarchy and initial CRLs, generate certificate requests with widely used web browsers, provides a search tool for client certificates in the OpenSSL certificate database, download of client certificates/certificate revocation lists with appropriate MIME types, storing all certificate data in LDAP repositories, scripts for the handling of the certification process on a non-networked system holding the CA's private key(s) and fairly easy configuration based on the OpenSSL configuration file.
pyChing is a program that allows you to 'consult' the I Ching. The I Ching is an ancient Chinese book of wisdom, which, apart from being read as a book, has also traditionally been consulted as an oracle. pyChing allows you to perform an I Ching 'reading' using the coin oracle, and then look up a brief interpretation from the I Ching. pyChing is completely written in Python, a cross platform, object oriented, programming language, using the Tkinter interface to the Tk GUI toolkit.
PyGCS is a very stripped down MUD-like chat-server written entirely in Python. It has a single "room" and no large database to keep in memory and on disk. PyGCS has no embedded programming language. PyGCS is ideally meant to be a small multi-user real-time chat system for people who have a need to talk to more than one person at a time online. It fits somewhere in between the setup IRC uses (no walking between rooms so to speak) and the MUCK/MUSH/MOO style of server.
