Marriage between Windows Multipoint 2011 and DC-125

As a first time buyer and user, would you guide me to or send me an article that shows step by step instructions on how to setup a Windows Multipoint 2011 using DC-125?

What other software work best with the DC-125? Any idea of the price range of each will be appreciated.

Are there any free software out there that will work great with the DC-125 Plugable device? I am planning on opening a Cyber Cafe very soon.
