Hi,

I'd like to propose 2 talks:

Mutual credit schemes as an alternative to crisis ridden capitalism
and its failed banks:
I'm planning to kick off a project in May in Oxford called oxcred
(oxcred.org.uk). It will be a mutual credit scheme. It was inspired by
the TEM scheme in Volos, Greece. It will use the cyclos banking
software, (see cyclos.org). A fully working demo system is configured
and running at oxcred.org.uk. Sign up and I will approve your account
if you want to play around with the demo. You can also use the cyclos
android app available in the play store. You will originally have a
balance of +5 oxcreds, a credit limit of 10 oxcreds. A demurrage/
liquidity tax of 1% per month is automatically applied to the positive
balance of all accounts.

Federated VOIP:
A handful of companies maintain a strangle-hold on telecommunications
systems internationally. They also control large blocks of number
space. This is pretty arbitrary. We now have open source software such
as opensips, repro, kamailio etc that can replace large chunks of the
telephone network.
Over the last couple of years open source software phones have
improved greatly,(e.g. linphone and jitsi). we can use these to make
and receive calls assisted by the SIP server software listed above.
Critically these systems allow for federation. A user
alice at domain1.org can securely call a second user bob at domain2.org
using the above system. The inter-server signaling,(call set-up and
routing), is protected by TLS and the actual voice data is sent
directly between peers and can be encrypted with ZRTP. I'm hoping to
build a prototype system over the next fortnight. I will make test
accounts available to people when it is ready.

Cheers,
John
