I have to agree that currently we have no known theories with evidence to support FTL travel. I still have strong hopes for this but it won't happen in any time soon. To make it happen we had to ditch relativity and causality.
Relativity is a scientific theory though. It is unlikely to be going anywhere. I assume you know the difference between scientific theory and layman theory.
Causality might not be a law that must be obeyed. However, we have never ever observed an effect coming before a cause.

The plasma wouldn't need to be very hot, so I would assume around 100,000-1,000,000 degrees of kelvin. I really don't know the size of the magnetic field either. The biggest problem is that the field would have to self sustain itself when the plasma bolt shoots off. This require a heavily magnetized material to go with the plasma bolt and sustain the field.
Remembering that hot gases like to expand, and that plasma is just a really hot gas, the plasma would push at the inside of the containment. Whatever is holding it together could not be on the inside otherwise it would get pulled apart by the expanding plasma.

OT: I believe an intelligent civilization would after enough time be able to do anything, but we can't imagine how we would use FTL with our known physics limitations. However, in the future, i believe we will pass that obstacle, as i stated that nothing is impossible.
Exactly my feelings about descovories. I also believe anything is possable.
That phrase is overrated. When the first law of thermodynamics was formulated, people stopped trying to create energy and rather just tried to recycle existing energy. "Nothing is impossible" was soon shattered when the second law was revealed. These machines are impossible.
The point is that just because we do not know something does not mean that if we discover it, it will be beneficial or pleasing. It could equally turn out that we finally discover these secrets and find out that FTL is absolutely prohibited, just like perpetual motion machines.
Sorry, i should have said it like this; most things are not impossible. Also, the laws of physics might change depending on where we are in the universe, or we might become so powerful that we can change them, or walk around them. There is also a possibility that it is completely prohibited, and the we have to use other means of interplanetary travel.
