I've deployed BigBlueButton to a Rackspace Cloud Server. Not terribly difficult but not exactly easy.<p>We're not using it in production yet, but during testing the system crashed after uploading 1 PPT but worked perfectly fine uploading another (both converted from Keynote) so I'm not sure if something was wrong with the conversion or there was some weird image in the ppt that screwed it up.<p>I'm still looking around / playing with different options.
