We need it. (I agree with John.)

It is not true. And you are not talking about "a directory".

Which search engines *look for* and *list* a multicast session which
has just started a few minutes ago?
(A multicast directory system should be more dynamic than a regular
web system. Therefore, there is nothing.)

How can we control *scopes* by search engines (or Web servers)?
(Central servers like Web server do not provide any means to define
and apply scopes to a multicast session. Therefore, it is impossible.)
