  Ooh, Ooh, I have something I can add to this discussion!  I read about 
the experiment of FTL and if I remember correctly, no physical laws were 
violated, but apparently it is possible to send information faster than 
light, but not the matter or energy.

The limit is actually on the sending of information.  Also, energy has
mass so tends to be restricted by the same rules as conventional matter,
with the exception that, in certain cases, the mass is finite at c.
True FTL communication would cause causaility problems as, to some
observers, reception would precede transmission.

Anyone demonstrating real information travelling faster than c would be
in for a fast track Nobel prize.

The trouble with the various experiments that you read about is that they
are relatively cheap but make very could press release material for the
popular science press because of the popular fascination with the possibility
of the speed of light limit being broken from people who never read the
actual science papers from the exeriments, which generally explain that
there is no new theory (typically over 50 years old) and no challenge
to the speed of light limit on information transfer.

The experiments aren't actually controversial at all, but they do make
good headlines, and good headlines are probably good for funding.
