Novell recently acquired a company called PlateSpin that does exactly this - 
currently the "live" functionality only works for Windows operating systems, 
but they're promising a version that will do Linux, soon, as well.  Linux can 
be done in the current version, but you have to bring the Linux system down - 
you can't do it on the fly.
