Yes that is right, that irritated me right from the beginning :) However it would mean that running multiple instances of Openmeetings in the same Tomcat Server is not possible because they all connect to the same context. But I think that is not true. I think you can run multiple webapps in Red5 and each of it has its own scope and can have its own RTMPT connection enabled.
