Some more thoughts on the one person making all proposals or distributing them.
One person makes the proposals (and controls the funds, you need to prove ownership of the payment address)
Pros:
easier to control all funds and have standard procedures
separation of manager and payments means that a manager can't go rogue because he can't mismanage and pay by himself
Cons:
less transparency on who is really responsible. We should be able to address this with more communication
concentrated risk... if a bus hits
@babygiraffe more funds are lost. It would also be sad because he's a really nice guy
Distributed proposals among project managers
Pros:
more transparency
Cons:
less control over funds and procedures
distributed risk means a lower chance of losing funds, but a higher chance of something happening
I would go with one person making the proposals, but clearly identifying who is responsible for each project. It is not possible yet, but at some time in the future I would try to use multisig addresses for proposal payments so we have distributed decisions and more security.
