I've put together a small jenkins plugin that will post the build results of a jenkins job to your lotus connections status.
A good bit of the inspiration came from here http://www.lbenitez.com/2009/11/updating-your-lotus-connections.html
You can find the plugin at https://wiki.jenkins-ci.org/display/JENKINS/Lotus+Connections+plugin
Information on Jenkins can be found here. http://jenkins-ci.org/
