I am running Minepeon without issue for a month now with Butterfly Little SC.
I have also TPLink router with DDWRT firmware where I installed BFGMiner. But did not test it yet to run the mining there.
I like that the Minepeon gives remote monitoring of mining advantage option.
Not sure if it would be possible the same way easily with DDWRT and BFGMiner.
I like MinePeon, I really do, but I've given up on it.
The Pi just isn't fast enough. It can't proxy and run USB miners at the same time. Even with the DLink 7-port which is considered to be THE USB hub for the Pi. First my Block Erupter dies, then eventually the Jalapenos give up. Of course, the NIC on the Pi is USB, so that craps out eventually too. It's not a power issue, everything is running off a 750W ATX PSU.
Everything runs perfectly when attached to my TPLink router running OpenWRT with bfgminer 3.8.1 on it - the only difference I see is the TPLink's USB isn't broken, and it has a proper ethernet interface.
I'm still keen to test the BBB version of MinePeon, too.
