Ultimately, in the far and distant future, the problem of travel will be resolved by quantum physics. You need to get from A to B. As things stand, you must pass across the intervening space, enjoying the countryside if you will. We 'have a nice journey' - or not, as the case may be. However, using Brundle's principle (yea I know it was only a movie, but humour me) the ultimate traveller never does that. He is either at A or at B and nowhere else.
This happens with sub-atomic particles (electrons, etc) right now. Electrons easily move from inner to outer 'orbits' around the atomic nucleus, but they do not 'move' between these orbits. They are either at A or B but never between. They are powered by quantum energy, energy packets of specific size, no more no less. This is gained or lost by the electrons through thermodynamic changes within their parent system.
In that far, far distant future, I see no reason why the particles which make up our atoms cannot be 'moved' from A to B by applying Terajoules of quantum energy in some form of 'Brundle cage'.
