BTW, a quick consideration - it might not be too late to briefly postpone the launch in order to setup a board of directors for the project and setting up m-of-n addresses.
I would happily serve in such a board, as I'm sure other trusted members of the community - you might gain more trust in MasterCoin by removing yourself as a benevolent dictator / point of failure.
You could also take the extra 1-2 weeks to revise and publically review the protocol.
After waiting so much time, why the sudden rush to execute without a proper public review process?
I did a co-founder search awhile back:

The protocol may change as it gets implemented. Right now is just the fund-raiser. I agree it would be cool to have multiple people helping me hold the coins. I approached several people about helping me hold the coins m-of-n style, but they were all too busy.
