Xmpp

XMPP / Jabber: WHY?!

With this protocol (xmpp == jabber) you can chat with other people that have such an account. Not neccessarily on the nurdspace server; any account will do. As the nurdspace server uses ssl/tls/something-encryption, it should be safe as well to use. Only when someone hacks either the nurdspace-xmpp-server or the xmpp-server of the opponent you're chatting with (well or your computer or the computer of the opponent), only then your messages can be read.

It is also convenient to have if you want people in #nurds (irc) to be able to send you a message by using "!summon nickname text" (contact flok for that).
