I think these algos could do very well with a boost.

You willing to pay $150 + possible fee for each? SP is no longer interested in open source. I myself am hoping alexis makes a return to github. 10 months old and still the some of the greatest work I've seen, free and without ego.

Thing about open source developers is they don't get paid (usually), meaning there isn't any incentive to do it. That's why you pay people like SP so they keep doing it, it doesn't go completely private, and then you get screwed by private kernel farm owners. You can look at the development of Equihash miners for Nvidia as a pretty good example of that. This thread used to be constant bitching by developers about how they don't get donations, now it's just bitching at SP for getting paid for his work.
Hope doesn't keep businesses alive.
