Zerberus is a, now discontinued, mail and news application, programmed in 1984, which was at the basis of the ZaMir Transnational Network in Ex-Yugoslavia.
ZaMir (for peace) was an electronic mail network in the geographical
region of former Yugoslavia especially dedicated to helping peace
oriented people and groups, humanitarian organisations, NGO's and the
independent media in order to improve their communication possibilities.
The network was open to all who want to use it.
