I like the current payment model. A consistent flow of payouts is just fine with me. Mine On With Kano-San
I do also. I think it came about because folks were complaining about the large number of small payouts in their wallets causing larger fees whey they tried to spend their BTC. Kano's accounting module for dust payout would also allow time intervals for the payouts to get fewer and larger payouts.
Right now fees are practically zilch, if fees every jump back up to December levels, we'd probably have to revisit this issue.
