I suggest that we ask maaku if he’d get on board. maaku is an experienced Bitcoin developer, who has been (?) working an a project somewhat similar to Mastercoin (Freimarkets), but which didn't get crowd‐funded as he hoped. maaku has been earning money from community donations, etc., and I expect that he'd strongly consider filling a salaried position as a Mastercoin developer. See his Github account.

We also might consider Vitalik Buterin (who wrote Pybitcointools and has demonstrated in interest in Mastercoin) and/or one/more of the other Dark Wallet devs—that project has only raised about $100k, so they can't all be working on it full-time.

In any case, we do need to be looking outside of the Mastercoin project for developers: Tachikoma and zathras have repeatedly stated that they're not for hire (though I would support hiring Bitoy, grazcoin and/or rbdrbd); we have thousands of bitcoins in the bank and a very cool project—we shouldn't be begging for time commitments.
