In the case of David Zimbeck, he is his own man and BlackHalo is his baby, neither BlackCoin, nor the BlackCoin Foundation have any say so in what is or is not included. David has represented BlackCoin at various functions this summer, but both Halo projects are his. To me, it appears David is out to change the world on his terms and as of now, it appears he wants to do that in his own way. I am beyond ecstatic that David chose to build his program on the BlackCoin platform, but that was his call as is everything he is currently doing with it. He is coordinating with the foundation and you can expect to hear some surprising news out of David soon.
At end best option to "Donate" is using creating services and donating by low fees if someone like David is making soft he can add %fee that can be changed or turned off anyway for end user is best when he donate small amount and keep software he is using up to date and bug free.
This is best "commercial" option and fair for all.
Foundation need find their way to operate and such mining found is not bad but i prefer direct backup projects like halo coinkite will be best option always.
I hope for foundation minig will be on big + and those guys will have stable way of founding.
