[Arm-netbook] AC to DC power adapter with multiple outputs

Hi all,

I am probably once again asking for something that is not there, but anyway. I'm currently hacking on several single board computers. Each of them requires 12V. So I would need an AC to DC power adapter for each. Each of adapters will require a separate socket in my master plug. What I would like to have is _one_ AC to DC adapter with multiple outputs to which I then connect my boards. Basically something like a USB hub but for power supply. After much of googling I wasn't able to find something like this. Have I missed something?

Thanks, Arokux
