[Skunkworks] Streaming meetings online

Hi people, for sometime now,we have been streaming our meetings via ustream and watershed to staff in our regions. My concern is on the video output as we normally use webcams hence the video quality is not that good specially on a larger audience. We shall be having a conference very soon and would like to stream preferably using a video camera. what accessories/apps/equipments would i require for streaming using a video camera? cheers! -- WALLACE NGENE TARURU wallacengene@gmail.com
