RE: Proposals with Payment on Delivery on Hive. How I would do it.

Yes, your process is simple and I like it for some cases (and I believe it was even used, apart from the poll part). The only problem I see with it is that it's often difficult to gather support when needed (even harder twice), and if we are talking about bigger payments, they can't be paid out all at once due to the daily limit for payments made from the DHF.

The daily limit is generally not an issue if payments are made regularly in an escrow account, and it is less likely, in my opinion, to do the work according to the specifications described when the proposal was made and not get paid if there is this mechanism of delivery check at the end.
