I'm also hoping to hear some feedback on the linux version. Is it even useful? The last commit for the Linux codebase was Nov 4, 2014, while the Windows version was updated 6 hours ago, and all the positive feedback from a few cursory searches seems to be for the Windows version.
 
It seems like if the linux driver had value it would be in wider use by now, and already incorporated into EthOS if it was going to happen?

But maybe we just need to be the gravel underfoot to give the linux version more traction? I'd really like to know why it hasn't taken off and I plan to look into this more.
