I have learned a little more about the way hard forks and consensus work in Steem, and the more I learn, the less convinced I am that @jerrybanfield's approach will bring the results that we are looking for.
If there is strong super for budget proisals, it would work better to build an SMT that coordinates it. People in support of proposals can buy the SMT to gain voting power on proposals and the initial round can be funded using the Steem raised in the ICO. It could have a fixed post-ico creation rate to generate subsequent budget. Then if all goes well we could get whales and top 20 witnesses to commit supporting that market to keep allocating Steem to budget proposals.
All the voting mechanisms, accounting schedules, and monitoring controls needed can be built into the SMT protocol without a hard fork in the blockchain.
