Python Desktop Server
The Python Desktop Server is a combined weblog and aggregator much in the Spirit of Radio Userland, but implemented in 100% Python. It needs a community server like PyCS or some FTP server (comments and trackback currently only work in conjunction with a community server) to host it's weblog. Alternatively it can be installed on a central host and just use a local Apache to publish the weblog. Main features are integrated cheetah templating, restructured text as alternative entry format, integrated desktop weblog, aggregator, wiki. It can be extended through your own plugins (called tools) and with macros and text nuggets. Author is GeorgBauer.
