A Very interesting interview with the bitwasp developers about DNM / Security / Future developments:
http://www.deepdotweb.com/2014/03/25/interview-with-bitwasp-founder-developer/
tl;dr (for those considering to create another marketplace):
Any Bitwasp implementation running a live wallet is taking unnecessary risks with user funds.
Yes, there are Bounties
"We clearly say that it is not finished, is still being developed and to use on testnet only. Unfortunately some have falsely claimed to have fixed issues which lead to people losing their money or privacy. "
The Good news: From beta version - No wallets, No balances, P2SH/Multisig Built in (added screenshots from the unreleased version)
Good bullet points!
