Finally finished going through the whole process to get a work project released as open source, check it out: http://sourceforge.net/p/rsseventmanager
We wanted a tool that would let us push events to an RSS server through a REST API. We modified our build scripts to use curl and send an HTTP Post to a server running a set of php scripts that I wrote. This replaces our old setup where we would send out constant emails to a list. It also means getting notified of events corresponding to a product is as easy as subscribing to an RSS feed.
I've been meaning to get involved in contributing to the open source world for a while and it feels good to finally get something out there :-)
