Demonstrating the value of virtual office technologies, Skype on Monday announced that it has filed papers with the Securities & Exchange Commission for a proposed initial public offering (IPO).

Skype, the real-time Internet communications platform that allows VoIP phone calls, instant messaging, video chat and desktop and file sharing, is hoping to raise $100 million.

Skype isn’t solely a virtual office technology, but the software is enabling the virtual office. Skype is one of the most popular instant messaging services available with 23 million users online at peak times of the day. This virtual office technology, as the company likes to say,  “connects business colleagues, saving them time and money and allowing them to stay ahead of the competition.”

Virtual office users can tap into Skype. Although web conferencing solutions offer a more robust experience, this virtual office technology sets the stage for GoToMeeting-like screen sharing and file sharing on the fly—and for free. That allows you to hold a conference call where all parties are looking at the same thing at the same time. You can even use this virtual office technology on your mobile phone by downloading an app for your BlackBerry, iPhone or Android-powered device.

But Skype’s IPO is more about the functions and features the company offers. Skype’s IP speaks to a larger trend in the marketplace. There is an increasing demand for virtual office technologies. Whether it’s Cisco’s WebEx, Citrix’s GoToMeeting or Skype, virtual office users and others in the world of work are relying more and more on technologies that drive productivity and collaboration.

What’s more, these technologies prove that collaboration is possible with a distributed workforce. Even if you have some employees in Manhattan, some in Miami and some in Los Angeles, you can tap into the power of virtual office technologies to get on the same page any time of the night or day with a few clicks on your computer keyword.
