Microsoft recently unveiled a developer portal focused on building support for its unified communications platforms including "Office Communications Server 2007". A common theme among vendors in the UC space is developing horizontal and vertical applications that can leverage UC capabilities such as integrated communications, presence, and role-based routing. In the Nemertes benchmark "Service Oriented Applications and Architectures" we noted that 58% of enterprise IT executives we interviewed noted that their organization were evaluating or already integrating unified communications with their SOA-based application initiatives.
