Given the length of time this discussion has been going on,
and the number of messages exchanged, is it not about time we
reached some conclusions. These lists are to advance the
deliverables in the working groups concerned, so how do any
conclusions affect those deliverables.
SIMPLE has a charter to produce instant messaging protocols.
I do not see in all the discussion of the advantages of
instant messaging versus real-time text removing that charter
item. Therefore I suggest we STOP that discussion, or the
proponents move it elsewhere.
SIMPLE does not have a charter item to produce real-time text
protocols. There is already an existing capability in IETF
for real-time text protocols. It is not really up to SIMPLE
to discuss whether that works well or not, as it was not
developed under SIMPLEs charter.
How terminals mix and match applications is not something
that IETF traditionally deals with. Therefore I would suggest
that any requirements that state RTT and IM must be
implemented in the same terminal are out of scope of IETF.
They should certainly be in some device specification rather
than in the MSRP specification which SIMPLE is specifically
delivering.
I guess the questions as affecting MSRP really fall down to these:
- Are there capabilities in MSRP that would lead to a
valid RTT protocol that works better than the existing IETF
solution, in addition to it fulfilling the requirements to
provide an IM protocol. From the exchange of messages I have
seem so far, it seems to me that the conclusion should be NO.
- In order to deal with a body of users that have IM, and
prefer to use IM, and a body of users that have RTT, and
prefer to use RTT, is there a need to be able to interwork
the two protocols at some intermediate point, and not just
within the terminal by supporting both protocols under a
common user interface? I see that as an element of the
discussion just raised by Paul. Does such interworking, if
required, have any impact on the contents of MSRP?

Never say never.
Have you tried interactive text/real-time text?
Did you?
First try it and THEN you can say if you like it or not.
If you want to determine how useful it is. Test it.
Use it
Try it
Compare it with IM.
See the differences between IM and RTT/Interactive text.
See that both text communication methods have their advantages and
disadvantages.
And use both for the best situations.
And if you still don't want to use RTT/Interactive
text..fine..I just hope
that when I call you, that you can still receive my call.
Just use it only
when the other person uses Interactive text/RTT.
Even if it is then 3-4 times per year.
Can you with IM:
* directly call the other?
* forward the call?
* put on hold?
* have the call go to multiple terminals?
* not being logged on a buddy list server, where you may get
flooded by 20
users at the same time saying hi! And such?
* being able to leave a message on an answering machine?
* using a service that allows a ring notifivation as soon the
other user is
ready with his/her other phonecall? (ring back on busy).
There are more.. but I am unfamiliar with voice calls. I am
just enjoying my
freedom of communications beyond the IM limitations.
And I enjoy using IM also..even though I am forced to use
Trillian, since
there is NO one universal standard for IM right now!
Interactive text is!
