Its even worse than this , not only are you charging for software that could be worthless 6-10 months your outdated 7950 and 280x gpus on your site are pretty bad for mining Eth in the next few months with the rising DAG size. Right now a 280x only hashes at around 22mh/s down from 26 a few months ago and a 7950 like 18 mh/s
The cards to buy right now are 380 series cards or Nvida since they have more memory and bandwith to handle the larger dag for a lot longer time.
the 7900 series cards will be useless to mine Ethereum in about three months due to the amout of power/hash
This is a lot of disinformation. Even with DAG size increasing, the best hash/cost GPUs are still the tahiti HD 7950/7970 R9 280/x. If you would like to buy a $400 GTX 980 to mine 12MH/s on it, please be my guest and do it on Windows. ethOS is for people who build farms, not gamers who take a break playing league of legends to mine crypto. You are not the target market.

https://github.com/ethereum/wiki/wiki/Ethash-Design-RationaleQUOTE FROM SITE:The ~0.73x per year growth level was chosen to roughly be balanced with Moore's law increases at least initially (exponential growth has a risk of overshooting Moore's law, leading to a situation where mining requires very large amounts of memory and ordinary GPUs are no longer usable for mining).
Since DAG file is 1.3gb now, in one year, according to above design rationale, it will be 2.24GB, which is
way lower than 3GB. Therefore, it makes no sense to buy any GPU that has over 3GB of VRAM. In fact, the mining period will end before the DAG reaches 3GB.
PS. I am not charging for software, according to GLP license (
http://www.gnu.org/philosophy/selling.en.html). Instead, I am charging for the distribution method and for support, which is extremely common in the linux world (both Ubuntu and Redhat follow portions of this model). You would be surprised how many people would rather not make a ton of ssd clones for their farm.
