I'd like to see there be some decentralization and a backup plan should Gerber's parachute not open. That to me is the most important point of these.

Next, I'd like to see the SIM pegged much more robustly to .005. To do that, I think allocating a percentage of card sales to an automated market maker would work quite well. The automated market maker would then create significantly more liquidity around the .005 peg for buyers and sellers to move in and out of the market without moving the price significantly.
