Four Skypes in one box
I thought of this question one day. “We have these four versions of Skype. For [Windows](http://www.skype.com/download/skype/windows/), [Mac OS X](http://www.skype.com/download/skype/macosx/), [Linux](http://www.skype.com/download/skype/linux/), and [Windows Mobile](http://www.skype.com/download/skype/mobile/). Can you run all of them _in one computer_ and have them talk to each other?”
Turns out you can, and it’s not so hard these days. As computers get more powerful, we see the virtualization technology get more popular, where you can run one operating system _inside another operating system_. On Mac OS X, the [Parallels](http://www.parallels.com/en/download/desktop/) product is a popular way of doing this, and it’s easy to install and get going with.
So I just created myself two virtual machines, one for Windows and one for Linux. And inside the Windows “machine”, I created _another_ machine using the [Microsoft Device Emulator](http://www.microsoft.com/downloads/details.aspx?FamilyId=C62D54A5-183A-4A1E-A7E2-CC500ED1F19A&displaylang=en). You can use this MS emulator to run virtual Pocket PC or Smartphone devices inside Windows, and also install applications such as Skype on them.
So here’s what it looked like. Click on the picture to see the annotated version and then you can also access the full-size version.
I had some trouble getting the Windows Mobile version talk to the others, and it didn’t start working until I used a different Skype Name from the mobile thing. I have also tried voice — not having the both call parties on the same computer, but just calling out from different versions. All of them work fine except the Windows Mobile version that needs to deal with double-emulated processor and there doesn’t seem to be enough processing power for this.
Anyone up for getting more than four Skypes on the same picture? Let me know when you do that maybe trying with different Skype cordless/wifi phones or other gadgets.
