There's nothing special about osu! installs. You can copy an installation anywhere and run it from any computer (assuming the configuration is compatible across the systems).

Like for example, later when I get time I am going to try to run osu! on my ubuntu machine, if I get it working, could I potentially just port the bottle over to my os x machine and try it out?
