Nilsson;
I doubt that you will find support from IETF folks for something that
breaks the end-to-end model of IP (as Imode and WAP do as they are
implemented today). I want to be able to ssh to my phone (or
equivalent). Anything below that is just telephantisms.
I'm afraid that ssh for phone is just another telephantisms. :-)
If you want phone with real Internet style, see our INET paper:
http://www.isoc.org/inet2000/cdproceedings/4a/4a_3.htm
The "Simple Internet Phone" has an architecture tuned for
a future situation in which non-Internet networks, such
as IP-based private telephone networks, will disappear.
While the "Simple Internet Phone" is a form of voice over
Internet Protocol (VoIP), most, if not all, VoIP protocols
are designed placing the priority in the affinity to the
telephone network. However, it is obvious that the telephone
network will be replaced by the Internet, and will eventually
disappear. At that time, most of the features of VoIP protocols
will become obsolete. Instead, the "Simple Internet Phone" is
designed placing the priority in the affinity to the Internet
and its architectural principles as an "end-to-end," "globally
connected" and "scalable" IP network. As a result, most
features of VoIP are substituted by the existing Internet
protocols. With Internet phones, callees are required to have
persistent connection to the Internet with globally unique
addresses, which helps to promote the healthy development
of the Internet.
Dispite all the hypes of VoIP people on QoS with private IP network
(if you are hyped, your phone can not be free and can not compete
with telephone network), I just confirmed voice quality good enough
between Taiwan and Japan through USA.
Run this kind of protocol over Ricochet terminal and WAP and iMODE
will disapper.
