Actually, I'm going to have to take issue with the acceleration beyond the
speed of light bit being impossible.  ;)

Physics Geeking TIME!

There seems to be at least two ways to get around the speed of light barrier
set up by Einstein and his Relativity equations.  The first has been experimentally
observed; it's called the Casimir Effect.  The second is just theory currently,
requiring things that are projected but not observed yet.

The Casimir Effect takes place between two charged plates.  (VERY charged plates)
In between those plates the speed of light has been observed to be noticeabley
faster.  (<30 m/s faster).  They are trying to explain this, because the speed
of light is assumed to be a constant EVERYWHERE in a vacuum.  The best one to
date that doesn't throw out Relativity is that the quantum foam between the 
plates is 'cleaner' with less virtual particles popping in and out of existance.
..which they can't explain why that would be either...The rest of the e
explanantions shoot relativity in the foot...;)

The next way was proposed by a Mexican Grad student at a Welsh University
(Albuquirre???).  He proved a way to go faster than the speed of light without
violating relativity.  Bloodyy brilliant, I say!!  He's stirred up a hornet's
nest.  It requires moving SPACE itself...nothing with mass can go faster than
the speed of light and the shortest amount of time between two objects is
the speed of light, but if you up and move a chunk of space where the speed of
light is constant still internallly...;)  It requires a massiive positive mass
(x jupiter masses) in front of the ship and a equally massive NEGATIVE mass
(not antimatter...negative matter...the stuff you open up wormholes with) behind
you.  You don't experience acceleration (space is moving, 'not' you) and no time
dialation takes place as well as unlimited speeds are theoretically possible...
A nifty little twist I came up with is that you can use it as a 'weak' force field.
Geoffrey Landis and I discussed it and it works nicely...at mutliple earth masses
instead of jupiter...(4x earth and you can repell anythiing moving up to 20%
of the speed of light....).

Anyways...I can babble more about itt, but if you want that....email me or 
encourage me...
