Thank you for this very helpful walkthrough. It works well.
I set the SEND_MINIMUM_FEE to 0 in reJ and although multibit still requires a 0.0001 btc transaction fee, this is at least 5-10x less than the standard fee. My transaction had 1 confirmation within 2 minutes.
Yeah, you are right. I've noticed the same thing later. There is another place you need to change things to get it down to 0 for sure. I don't remember right now but if someone really needs this, I might try to remember.
I've made lots of changes to Multibit, there seems to be an "estimated fee" calculation that I cannot bypass yet. I am able to set a 0-fee transaction, but have to set the send amount to be 0.0001 less than the full wallet amount.
Either way, with just your 1 patch cure, I was able to reduce the transaction fee to sweep my mining address from 0.0016 down to 0.0001 btc
Edit : just sent 2 x 0 fee transactions, 1405 (bytes) and 15270 (bytes) - which unmodified multibit would have required 0.0002 btc and 0.0016 btc transaction fees.
Both were confirmed in the 2nd earliest possible block, with 0 transaction fee. (there were approx 1300 unconfirmed transactions on the network at the time)
