I have been using minepeon on my RPi. I started with some ASICMiner erupters but I sold them, now I have some of my BFL Jalapenos running on it.
There you can find all the information and links you need to get your hardware up an running.
I'm not concerned about software, that isn't too hard. What's bothering me is hardware. I dont really know what ASIC to run. I hear BFL is just terrible.
You can try looking at these ASICs:Bit Fury (2.2-2.6 GH/s),Ant Miner U1(1.6-2.2GH/s),Bi Fury(around 5GH/s),etc as they'll work with MinePeon without trouble.Hope this helps you with your search
Edit:Added hash rates of each respective ASIC I suggested.
