SILC [ Secure Internet Live Conferencing ] sounds like it could be mighty handy for a number situations:
“SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet over insecure channel. SILC superficially resembles IRC, although they are very different internally. They both provide conferencing services and have almost same set of commands. Other than that, they are nothing alike. The SILC is secure and the network model is entirely different compared to IRC.”
“SILC is much more than just about `encrypting the traffic’. That is easy enough to do with IRC and SSL hybrids, but even then the entire network cannot be secured, only part of it. SILC provides security services, such as sending private messages entirely secure; no one can see the message except you and the real receiver of the message. SILC also provides same functionality for channels; no one except those clients joined to the channel may see the messages destined to the channel. Communication between client and server is also secured with session keys and all commands, authentication data (such as passwords etc.) and other traffic is entirely secured. The entire network, and all parts of it, is secured. We are not aware of any other conferencing protocol providing same features at the present time.”
i think a jabber transport could be fun.
