The purpose is to have a USB flash to have a developer seat everywhere. The idea is to use application virtualization to package Visual Studio.
However, AFAIK, there are big problems.
Have anyone succeeded in packaging Visual Studio (2010, 2008) using ThinApp, App-V, ...
P.S. I'm aware of google.
This is not possible. There's nothing "thin" about Visual Studio, it has an enormous mass of files in many different directories and a very large number of critical registry entries. Including many COM components. That it works as well as it does is one of the modern day's Seven World Wonders of software engineering.
Your license allows you to install VS on more than one machine as long as only one user uses it. I recommend you take advantage of it.
