These might be the droids you're looking for:

But, the hardware is not widely available at this point. I don't know if/when the hardware will be up for sale.
So, to answer some previous questions. Will it be made open source? It is. Will it be offered as a product? Presumably some day.
The connector is horrifically expensive ($2500 to $3500) so I don't see it being put on a motorcycle. Also, I'm sure Damien can attest that Chademo chargers tend to not deal well with low voltage vehicles. You really want to have 300-400V if you're going to use CHAdeMO.
So, right now it's sort of the wild west. There is source code you can look at. You can cobble together the hardware. You can then slap it all together and get it to work. But, there isn't a nice generalized commercial solution right now. I think that EVTV will end up making it into a product at some point. There's lots of irons in the fire right now so I can't really speculate when that might happen.
EDIT: I suppose I should mention: We're talking about a lot of power here. You could kill yourself, burn your car up, or accidentally start the great fire of 2015 in your home town. Be sure you know what you're doing if you start to mess with CHAdeMO and that sort of power level. That said, it's less power than EVs tend to use anyway. Just be careful. You screw up a $30k charger and you won't like it.
