You are correct.  People do call IM real-time.   But I was asking that we not 
do so.   The definition of 'real-time' by the ITU covers Real-time text but not 
IM.    And there are important reasons for the definition -- and for not 
calling IM real time.  IM can take a very long time before anything is sent for 
slow typing users (and if the person doesn’t or can't hit the return - it is 
never sent)  -- whereas real-time text is guaranteed to be sent continuously 
with only slight batching for efficiency.   

There are now requirements being created in communication and emergency 
specifications - that use RTT as the designator for what is needed (so that 
they don't have to specify a single standard for all platforms).  So it is 
important that real-time text communication not be confused with IM.

Hence the request that we try to avoid that going forward. 

Thanks.
