The group will be headed by Anoop Gupta, who now serves as the technical advisor to chief software architect Bill Gates.\u201cClearly Microsoft sees conferencing and collaboration as an important part of its future,\u201d says Andrew Davis, an analyst with Wainhouse Research. \u201cThis is a major step into the conferencing and real-time collaboration market.\u201dAccording to Wainhouse, PlaceWare is the No. 2 player in the Web conferencing service provider market but has been losing ground to leader Web Ex over the past year.Davis warned that Microsoft the product company has a poor track record as a services company. \u201cMy concern as a PlaceWare customer would be that I continue to still get the same level of service now that the service company is run by a software company.\u201dMicrosoft said its plans to turn conferencing into another ubiquitous technology.\u201cSuccess for us is that we make Web conferencing as easy to use as e-mail,\u201d says Charlie Zaragoza, lead product manager at Microsoft. \u201cPlaceWare brings talent and intellectual property to help us do that.\u201d Part of that technology includes a patent acquired in 2001 for PlaceWare\u2019s bi-directional byte stream protocol, which allows conferencing traffic to traverse a corporate firewall without compromising the security it provides.Zaragoza says Microsoft plans to continue to run PlaceWare as an online service and that it will be incorporated into its real-time collaboration plans.But clearly, changes in the market are underfoot. Corporate customers are no longer looking at Web conferencing as an al a carte service and are making strategic decisions about its use to improve collaboration and cut costs.PlaceWare\u2019s big rivals Web Ex and Raindance are trying to promote Web conferencing as a standalone application that has real-time collaboration benefits. That view is contrasted by vendors such as Microsoft and IBM, with its Lotus Sametime server, which see conferencing as merely a component in a suite of collaboration offerings that run on their platforms.\u201cMicrosoft\u2019s move to acquire PlaceWare does signal a first step that consolidation is now taking place,\u201d says Leon Navickas, CEO of Centra, which develops real-time e-learning software for corporations. \u201cMy guess is that WebEx and Raindance have a lot of work ahead of them. They thought the opportunity was to create Web conferencing services but the competition just got a lot stiffer and it\u2019s competition that will bring price pressures.\u201d From his point of view, Navickas says Web conferencing is just an enabling technology and that Microsoft is turning that technology into a commodity that Centra and others can build applications on top of for corporate customers. \u201cWe\u2019ll use instant messaging, databases, Web conferencing and all the other tools to build our new applications,\u201d he says.Microsoft\u2019s current collaboration tools include Exchange Server and Exchange Conferencing Server as part of its real-time collaboration offerings. It also has Messenger in Windows XP that offers instant messaging and options to add voice and video for use with other XP desktops.Microsoft plans to release later this year a set of real-time technologies code-named Greenwich that will become part of Windows Server 2003 and include instant messaging, conferencing, voice and video.Those offerings overlap with PlaceWare, which just last fall introduced its first software for deployment on corporate networks called On-Site Solution. Zaragoza said the details are still being worked out as to the future of that product and how PlaceWare will fit in with Microsoft\u2019s .Net Web services initiative.He did say the company would offer a set of application programming interfaces (APIs) that will allow software developers to extend the conferencing platform Microsoft is trying to build.\u201cToday we have XML-based APIs and we will look to further that through the use of Web services standards,\u201d says Jennifer Callison, senior director of product marketing for PlaceWare.Microsoft said it expects the acquisition to close sometime in the middle of this year.
