jabberlib is a Processing library that encapsulates the SMACK API, an “Open Source XMPP (Jabber) client library for instant messaging and presence”. I startet development as part of the Time Inventors’ Kabinet (TIK). TIK is an art project interested into ecology and media art, a collaborative experiment with time. jabberlib is based on SMACK as our TAK server relies on the XMPP pubsub service.
The current version 0.2 is really basic and more like a proof of concept for using SMACK as XMPP client with Processing. Documentation, examples and download from here.
