Sorry, I meant an escrow for the funds (ETH) transferred to Tribe's contract address (rather than the tokens we receive). As it stands there is nothing preventing an ICO from taking all the money and running away (no offense to you guys).
To be honest with an escrow the same thing can happen in some way. We like to build upon trust and be as public as possible with code and communication. I understand your points. Look into the idea and see if you like it. That's what I recommend for any project.
