Hi everybody,
recently, I found a cool tool: USBwebserver.
It is light weight webserver stack with apache2, php5 and mysql5 that fits on every USB stick and can be started with a simple double click on the exe if you run a Windows machine.
As all system requirements seem to fit from scratch, I copied the beta version of OXID eShop 4.5.0 on it. You can download it here:

It is perfect if you have to show your OXID eShop mirror to others or even for development purposes.
Good luck checking this great tool!
