Are there anyone out there who would like to volunteers to help us make “XBMC Portable” for us, a PortableApps.com USB Edition of XBMC for Windows?
PortableApps.com works similar to U3, the main difference is that PortableApps.com is free and open source , and it also works with any with any portable USB Mass Storage Device for Windows (USB flash drive, iPod, portable harddrive, etc) . Checkout the wikipedia article about it.
The storage device would not be bootable but it would be very cool to do a quick demo of XBMC on any of your friend’s Microsoft Windows computer with it, simply plug-in the USB storage device in any Windows XP or Vista computer and XBMC is ready to be used.
Discussion about this can be found in the XBMC Community Forum.
