"In summary, there is an opportunity for improved collaboration across a company that can drive new levels of productivity and employee satisfaction," he wrote.

The recent acquisitions are geared toward helping VMware enable this kind of collaboration.

In addition to Socialcast, VMware this year has purchased SlideRocket and Zimbra. Zimbra offers an e-mail and collaboration suite of products, and SlideRocket lets users create and share PowerPoint presentations.

VMware did not disclose the value of the Socialcast acquisition. Socialcast customers include Nokia, Avaya, Humana, Philips Electronics, SAS and, recently, VMware.
