Team,
Here is my strawman:


The convergence of wireless communications and the miniaturization of
computing platforms have resulted in a class of mobile devices that offer
high resolution displays, application programs with Graphical User
Interfaces, and access to the internet through full function web browsers.
Devices that were once "mere" cellular phones now support most of the
function of a laptop computer. However, the trend that makes the technology
possible and commercially successful, miniaturization, also creates a user
interface "bottleneck." Tiny displays and keypads are significant barriers
to the usability of application programs. Multimodal user interfaces, i.e.,
UIs that offer multiple modes of interaction have been developed that
greatly enhance the usability of mobile devices. In particular, Multimodal
UIs that combine speech and graphical I/O are prving themselves in the
marketplace. However, there are a class of mobile devices that do not
provide the computing resources to perform speech recognition and synthesis
locally on the device. For this class of device it is necessary to
distribute the speech modality to a server in the network.

The Distributed Multimodal Working Group will develop the protocols
necessary to control, coordinate, and synchronize distributed modalities in
a distributed Multimodal system. There are several protocols and standards
necessary to implement such a system including DSR and AMR speech
compression, session control, and media streaming. However, the DM WG will
focus exclusively on the syncronization of modalities being rendered across
a network, in particular Graphical User Interface and Voice Servers.

The DM WG will develop an RFC that details the architectural requirements
of a Distributed Multimodal system and the logical message set to effect
synchronization between modalities. It will investigate existing protocols
for the transport of the logical syncronization messages and develop an RFC
detailing the message format for commercial alternatives, including,
possibly, HTTP and SIP.

The protocol will assume RTP for carriage of media, SIP and SDP for session
control, and DSR and AMR for speech compression. The working group will no
consider the authoring of applications as it will be assumed that this will
be done with existing W3C markup standards such as XHTML and VoiceXML and
commercial programming languages like Java and C/C++.

It is expected that we will coordinate our work in the IETF with theW3C
Mutlimodal Interaction Work Group.


thanks,
chris
