I guess that's all what we have left to do until April 2011. :)

Possible dark and anti-dark matter speculation to throw into the stew ...

Out of the energy. This is simple matter/anti-matter pair creation. Been in textbooks for 50 years, I can't see what's novel here save that they did some new calcs. I did a 40 page paper on this as a junior in high school, more than 30 years ago.
thats what I understood as well... whats so new about E=mc²? Thats why I feel there must be something I am missing in this experiment because everyone is so excited about it. But so far, only thing I understood is that they converted a lot of energy into matter+antimatter.

that is really much more of a 'breakthough hypothesis' - good find.

they claim its also testable:
...If physicists at SuperKamiokande went back through their data and looked at slightly different energies, they may be able to find traces of dark matter...
and then...
...The signature of dark matter destroying protons “can be easily tested by the even bigger proposed underground detectors” planned to be built somewhere in Europe...
oh well, round and round we go... they'd better also discover a large quantity of dark-cash then, or possibly quantum junk bonds to pay for it.

Antimatter augmented fusion has been proposed for decades. The problems are considerable. How much fusion will be induced with a given amount of antimatter. If you expend 10 gagawatts to make 1 gigawatt worth of antimatter (10% efficiency) and this results in 5 gigawatts of net fusion power, you are stuck. But if you can increase the antimater creation efficiency, you might reach breakeven in this purely speculative setup.
The other problem is how much antimatter you can make. Currently, despite massive particle acceleraters and decades of time, only tiny amounts of antimatter has been produced. Perhaps enough to provide for one power plant for 1 microsecond.

Perhaps this electron beam- laser approach scales better than huge particle collider approaches.
