with OpenMeetings 0.5.1 the Integration of OpenMeetings into different environments is not that hard!
I made the first step by creating two Plugins for Moodle (wide spreaded ELearning Platform). For installation and how-to see:

The Moodle Plugin is only a first step into integration here. It is possible to directly add as many Rooms of Type Conference of Audience into any Course you like. It Plugin uses the new SOAP-Gateway to get/set some values in the OpenMeetings API (http://code.google.com/p/openmeetings/wiki/SoapMethods). But it only uses 50% of the Methods available here, so extending the Plugin with new functionality should be quite easy.
