I was thinking about writing one, but 50 BTC "promised" in forum posts is nothing like 50 BTC in an escrow account. Get actual money into a kickstarter or indiegogo and it's a different story.
Show me devs competent of completing task and I will spend the painstaking time and effort to organize the escrow. Organizing the funds makes no sense if no one is agreeing or showing enough competence to complete task.
Get the funds together and Wolf0 and I might look into it. Until we have funds in escrow, though, we can't dedicate time towards it.
