The MIT Zephyr Notification system is something I worked on in the late 1980's, and 20+ years later it is still supported and used (in a fairly narrow niche.) For historical reasons, there is a small niche of users within that niche who treat Zephyr as their primary instant messaging platform, and gateway other things to it; thus, a Twitter gateway and posting client. ztwitgw takes the timeline, replies, and favorites, and sends them as individual "ZephyrGrams". It was recently ported to tweepy in order to get Oauth support; this works, but I still haven't figured out how to not-distribute the consumer_secret. zpost is like the classic Zephyr "zwrite" - an easy to use fire-and-forget message sender, the kind of thing that made it easy to integrate notification into everything (print queuing, builder loops, test loops, anything you could run a shell command from.) My biggest current use of it is for posting summaries of picture-upload batches directly from my kphotoalbum flickr upload tool. It's also now on tweepy, with the same caveats about consumer_secret. (See README-thok or the upstream link for dev history; this was pulled in to github using git-cvsimport.)
