I'll pledge .35 btc too (the same as I've just spent on 700 ETH).  I much prefer the spin-offs approach but also realise there's a lot to figure out yet. I guess cash incentive may add to the motivation of those capable of making this happen which is why I'm chipping in on this one.  So I'm backing two horses in this race And yes, I'm up for making my bounty pledge official on Buntysource or wherever
