Two A few questions:

• will your driver and/or mining software be open source?
• In the case where GPL code is used, will you respect the license and post your modifications? You know, unlike your competitors (I'm looking at you bitmain and lketc  ).
• will you make your circuit schematic docs open source - or at least available as PDF?

If the answer to the above questions is 'no' how exactly do you expect customers to maintain/repair your products?

One more question: how long do you plan to support the product e.g. firmware updates for bug fixes, new miner software versions, and performance improvements?
