The main problem with SIP and others is that the sender cannot be
correctly verified without PKI or similar systems. SPAMmers can send
their stuff semi-anonymously.

I have developed an early draft on a protocol that could overcome this
problem without having to implement and agree on a common PKI - and
with a spammer usually being at disadvantage bandwidth-wise.

Please have a look at http://xarsim.org/ - comments are highly
appreciated (yes, the messaging part currently is *very* rough).

Thanks a lot

Volker
