$WORK needs secure chat, which means we must run the server and have a fair amount of confidence in the clients. So we run an XMPP (ejabberd) server, with SSL/TLS required and no open registration.
All the open source groups that I know (with no particular security requirements) use existing IRC networks, mostly freenet. There is one set of discussion groups I know that uses Slack; I use the IRC interface to Slack to talk to them. Random friends tend to use Google Talk/Hangouts, which has an XMPP interface but doesn't federate. Pidgin handles all these protocols smoothly, so I don't have to think about which one I'm using except when I set it up. -dsr- _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
