Is it possible for XBMC to run standalone on for example an external hard drive?
I have got two laptops at home and would like to access the same XBMC database with both of them, without having to switch to the laptop I have installed XBMC on.

XBMC was really designed to be cross platform (i.e. portable) so its pretty good about keeping all its settings in a local file already.
