UPDATE: Today there were some little interruptions. For example Rigs showing offline/termporary offline. This is becasue i was optimizing server and doing some restarts of services.
I really like what you have done here, and I've been testing for a few weeks now. I have no problem paying a small fee for your work and upkeep of the software. If you were to go on holiday or something else, would someone be available to work on the software or hardware that this is based on in your absence? I think most miners would not be happy paying a subscription if there was a long downtime, especially some of the larger miners that might want to use this OS.
It's just something to consider, and I'm sure you'll take the correct precautions. Thanks again for putting this together. This makes it easy for "just-slightly-better-than-newbie" miners to get back in the game and experiment, or just let it run.
