Stan / bytemaster should publish a budget spreadsheet of how much BitUSD they think is necessary to run core operations for the quarter / year, broken down by TITAN account.
Then, every day a script sends an IOU UIA to each account for each dollar of shortfall between their budget and what they were able to earn directly from the DAC with their delegate(s).
For the paranoid, public information can allow a script to audit that the IOU issuance matches the budget. The IOU UIA can be issued by a multisig address signed by multiple trusted community members running independent copies of the script.
Then we get one or more new 100% delegate(s) who promise to use their newly created BTS (minus reasonable commission / expenses) to buy BitUSD, then create a buy wall at 1 IOU / BitUSD. Burning any IOU they obtain (or returning them to the issuer address, I think burning UIA is actually not implemented; see
https://github.com/BitShares/bitshares/issues/883 ).
Since the IOU is a UIA, there is no centralization issue simply letting bytemaster inflate as many IOU shares as he wants to and distribute them as he sees fit. If the shareholders agree that bytemaster's budget is fair and transparent, then they will elect 100% delegates to give the IOU a market valuation backed by the power of the BTS printing press. If the shareholders don't like the budget, they can simply kick out the delegates that support this scheme.
