We have tested your ZcaleRight program extensively during the development of the BBB cluster for the universities and schools of Rhineland-Palatinate, a federal state of Germany. ZcaleRight offers considerable advantages over the open source program Scalelite offered by blindsite networks. The scalability and the possibility to create server classes and to assign conferences according to different criteria (number of expected participants, importance of the event, group affiliation of the organizer) to this classes should be emphasized. Nevertheless, for non-technical reasons (we as a public institution are committed to the open source idea.), we have decided to continue using Scalelite. Especially because we have the capacity to actively participate in the development of Scalelite and thus to slowly adapt the stability and the range of functions to the level already reached by ZcaleRight. From a technical point of view, I can recommend the use of ZcaleRight.
