Lotus had adopted the SIMPLE protocol early in its branching off from SIP, and it still a work in progress.  Now, like many others, Lotus has adopted XMPP, the protocol behind Jabber as well.  This means that there is yet another mainstream product that is interoperable with other XMPP-based services, including APU IM and Google Talk.

It appears as though more of the industry is waking up to Presence Being the Killer App. With Jabber Inc. being a leader in this space. Jabber, Inc., which develops real-time communication server platforms for developing IM and presence-enabled applications, is fashioning its XCP platform into an application server of sorts not only for presence, but also for messaging, routing and XML-application development. In September, it will release a publish-and-subscribe technology called Information Broker for pushing content out to users.

Interesting too, is the increase in adoption of Enterprise IM (EIM) and consequent integration of presence in business applications. A recent Osterman Research study shows 44% of companies use IM with business applications, up from 21% just three years ago. Furthermore, 34% of users have standardized on an internally run IM platform, up from 24% just two years ago.

Jabber Inc. is has announced new versions of its commercial Jabber server and client.
