Linux is nice because if you have a separate home folder, after a fresh install you desktop is the same, shortcuts are the same, behaviour is the same, etc.

BUT, if you have another machine (me, for example, using desktop and laptop running the same mint edition), it is a lot more tricky and difficult to make the machines behave the same, and even to keep them behaving the same.

I should be nice to have some way of:

1) transfering some configuration of a running machine into a freshly installed new machine;

2) making an already running machine to inherit the configurations of another running machine;

3) have an option to continuously sync (via cloud server) the behaviour (configs) of the user's machines, in a "google toolbar" fashion. This would be necessary since we are always evolving the way we work with the computer, and learning some new tricks;

3) [optional] switch between different "user profiles", making it possible to use someone else's machine with our own configurations, and switch back after using it (maybe it should be better to have another user session which would load the profile from server).

I know it is not that easy, but would be definitely great!
