i would make the DAO escrow type of service pay on completed tasks.
user/dev makes a proposal/job (support votes reached = means start work but not payable until product delivered)
product delivered checked by the witness to reach a consensus for payment. 19/20 need to approve.
features auction type priced.
if increased all support reset.
if decreased no change.
use case
live events confirmation.
make witnesses work a little bit :)
attract outside devs looking for work.
good value.
