Microsoft is xmpp support to connect with Windows Live Messenger service. Until now had to third-party clients make use of reverse engineering to WLM-adding support.
Adding support for the open-source chatprotocol xmpp is for developers to easier support for Windows Live Messenger to add. Up until now supported Microsoft only a proprietary protocol; the other developers could not figure out how they support could add. Support Messenger third-party clients such as Pidgin and eBuddy, was therefore often of varying quality. It came for the Microsoft protocol change, which means that other chatapplicaties no longer working.
That must now be over. The xmpp-support of WLM also includes delayed delivery, so messages can also be sent when someone is offline. However, it is unclear whether there is also support for file transfers is present. Understand file transfers are currently poorly supported. For authentication is OAuth 2.0.
Or Windows Live Messenger, users can communicate with users of other xmpp services such as Google Talk, is not from the announcement made by Microsoft. Nor is known whether the Windows Live Messenger client itself also on xmpp upgrade or that Microsoft for its own client on a separate protocol. Incidentally, had Yahoo Messenger and Facebook more official integration with WLM; Microsoft previously worked together with the companies.
With the support for xmpp, Microsoft wants to use Windows Live Messenger probably promote. Microsoft’s im client was in the Netherlands for a long time hugely popular, but more and more people communicate mainly through social-networking sites like Facebook and mobile chat apps such as WhatsApp.
