Hello SuSE folkz,


First your wrong only public keys should be exchanged.
The list will have a public key which the subscribers will use to when
sending messages to the list. In turn the list will use the keys of the
user to encrypt messages to them and send them out.

Your risk comes from outside agents who would seek to capture the
server. Herein lies the risk which requires the use of memory not hard
drive to store the lists public and private keys. If they reside in
volatile memory then they can not be captured. If your really smart the
host will reside headless in a confined space with a proximity alarm
which reboots the server if the server is disturbed thus destroying the
list keys.

Using this protocol you have one final risk; picking who can be trusted
to join the list since anyone once joining will still be able to read
all messages but no business or government will be able.

This is the basis of the Spitzer protocol. I have discussed it only a
few times. No one has implemented it as of yet, though it would be
ideal for use by both government and political activists. It has one
primary risk as do all systems the people using it; who must be trusted
to be mindful PKI and physical security of their systems.

In this age of post 911 diminished freedom in America and increased,
unlawful spying on civilians outside America we should all have copies
of the source code and binaries of gnupg.
