Maybe you can talk Dan Larimer into doing the initial explanation on the technical details of how sidechains will work. Having him explain the code snippets would be enough for me to better formulate my articles with greater technical understanding and detail. I do know the capability exists to do it but I also know Atomic Cross Chain Transaction capabilities exist in Bitshares. So you can do it in many ways but it's about finding the optimal way which is mutually beneficial and which doesn't take away the blockchain independence from the Bitshares community if they want it because Bitshares is a sharedrop target which means it's part of a stigmergic operation in itself (evolved from Protoshares). Steemit is not.
