With bitcoind 0.9 the rules for tx fees are no more hard-coded. This is good. But it is hard for the nastyfans policy. It maybe not clear what tx fees to add to purchase order prices.

I ask for feedback on some ideas:

Maybe there is no tx fee added to purchase order prices. And payments to sellers are added to weekly distribution instead of separate transactions. This reduces purchase order costs but adds tx fee costs to the distributions.

Another idea is to set a fixed purchase order tx fee cost that goes into a new tx fee account. Payments to sellers are added to weekly distributions and the tx fee account is used to help pay distribution tx fee. This does not reduce purchase order costs but will reduce distribution costs.

Feedback appreciated.
