Remote Path / Local copy

What I would still really love to see in XBMC is the option to make a local copy from videos on a remote fileserver from inside XBMC, and without screwing up the library. Often I go watch a movie at a friends place, or take my laptop with my on holiday, and it's always messing around then with local copies and duplicate entries in the library.

Just a nice to have, foir an already awesome piece of software.
