We have produced a python script that can be used by anyone who wants to help make the BitUSD market and are looking for developers to help make it better!https://github.com/BitShares/bitshares_toolkit/tree/develop/programs/market_maker
It is a tad crude right now, but we have plans to make this kind of script configurable for anyone who wants to perform this function.
The rules are simple:
1) Buy BitUSD cheap (a few percent discount)
2) Sell BitUSD at the median price feed (or the latest feed from BTER) which ever is higher (in dollars per BTSX)
3) Adjust orders anytime they deviate from what the new orders would be by more than some tolerance.
Under this plan no *NEW* bitUSD will be created until the peg is hit *AND* everyone buying BitUSD can expect liquidity within just a few percent. Meanwhile profits can be made every time someone switches sides of the market.
We are providing the script for others so that we can increase liquidity and decrease the spread (as our bots compete against each other
Users can now purchase BitUSD with confidence that they can sell it when they need to.

You can tweak the parameters by editing:
SPREAD_PERCENT = 0.05 # 5%
TOLERANCE = 0.01 # should be less than SPREAD_PERCENT / 2, the closer the tolerance the more often orders are canceled/updated
MIN_USD_BALANCE = 10 #make sure you retain enough USD to pay fees to update your orders
MIN_BTSX_BALANCE = 100 # make sure you retain enough BTSX to pay fees to update your orders
MIN_USD_ORDER_SIZE = 2 # prevent dust orders
MIN_BTSX_ORDER_SIZE = 100 # minimum order size to prevent dust
MEDIAN_EDGE_MULTIPLE = 1.001 # how far in front of the median price feed do you want to sell.
