Cameyo - Creating Portable Applications

Ever wished you could pack an entire application into one single .EXE and take it with you anywhere without having to reinstall it every time?
At work, at home, on your laptop, at a friend...
Ever wanted to avoid having to reinstall all your applications every time you change, upgrade or reformat your computer?
Or, if you are an IT admin, have you ever dreamed you didn't have to test and deploy applications, and simply let your users launch them on demand whenever they needed to?

If so, application virtualization is probably what you need.
