The world of web-based communication just keeps getting better. On Monday night Meebo launched Meebo Platform, a service allowing third party application development for the browser-based IM site. According to TechCrunch:

Like Facebook Platform and the recently announced MySpace Platform it consists of a set of APIs to give developers access certain user features and information. Developers will be able to include Flash applets and Javascript snippets within the applications.

Unlike MySpace and Facebook, however, the platform is not open to all who choose to come. The company is announcing four partners this evening and opening up a sandbox area for developers to build potential applications. Those that Meebo thinks will make the user experience richer, will be permitted to launch.

The four initial partners are Pudding Media (voice chat), Tokbox (video/audio calls), Ustream (live broadcasting) and Talkshoe (group voice calls).

Assuming these and future applications become part of Meebo's widget service, MeeboMe, this could benefit libraries offering virtual reference service by enabling voice and video chat with patrons directly from the library website.
