There are many instant messaging solutions. Some of them are open source yet only a few rely on open and established protocols. Nonetheless utilizing open standards is a keystone to not just creating the next hype but to create a lasting solution that will outlive its competition.
XMPP is such a standard and has been around for over a decade. Unfortunately in the past XMPP had had a hard time adapting to the challenges of mobile and multi-device environments. However in the last 18 month the XMPP community was able to overcome a lot of these problems.
This talk is about how we solved the problems of unreliable connections, power consumption and message synchronization. It is also a talk about the remaining challenges and possible solutions.
