Do you mean that all MESSAGEs in a conference session share same call-id?

This can be done, but then you cannot do message identification.
It is impossible to refer to a specific MESSAGE anymore,
and I think this is required. (Referring to a conference discussion 
based on call-id is useful, but you may also want to refer to 
a specific IM inside a conference, especially when replying).

New header (message-id) would solve that problem.
It might make sense to create also References header.
This would allow that In-Reply-To always refers to a session,
while References refers to a specific MESSAGE.
