tl;dr - There's a thing called 'codec2'

digital radio performance at 1200bps (although 2400bps is better)
The thought bubble was: I wonder if/how/could (etc) OTR could be used
to provide encrypted open source digital radio.
Some background and thoughts:
In the Amateur Radio service, cryptography is (99.9%) not allowed. So
OTR and ham radio will not go together.
Ah rightio, as a non HAM operator I wasn't aware of this. That being
said, there's probably application in areas where such would be desired.
Immediately, I think of our local police force who ... well, long story,
but they're using closed and proprietary systems and our government's
the most broke in Australia (the ethics of the police force encrypting
general comms is a total aside to this, as follows). Whilst it may not
be usable by the HAM community, emergency services such as Fire and
Ambulance etc. might be able to make use of it. Also, in places of
severe civil unrest and no internet infrastructure, short burst
encrypted radio comms might be useful.

One could send codec output over TCP, inside XMPP.
One could send the codec output over a UDP stream, associated with
XMPP.
I would be interested in pointers to audio/video associated acht in
jabber.

Another thought bubble I had, albeit starting back at the LCA2013
conference, is getting pidgin-webkit to do HTML 5 video, particularly in
MUCs (see
http://mirror.linux.org.au/linux.conf.au/2013/ogv/Code_up_your_own_video_conference_in_HTML5.ogv
) for educational purposes (as the proprietary systems the local
University used when I tried attending drove me to dispair!) but
obviously the one-to-one would be useful as well.
I'm semi-committed to hacking on this with one of the more prolific
Pidgin plugin authors over the next few months. One thing I had already
though about would be investigating along the way would be how OTR could
hook in to this as well. However as I'm at about the same stage with
that as I was last night with my thought bubble. In deference to the
list, I've renamed this thread to look a bit more broadly at encrypting
voice/video somehow.
Pete.
