I'm not a fan of trying to increase the frequency of micropayments, but at today's rates 0.01 is ~$4, and I can see a user for being able to withdraw $1-3 (at the cost of a few pennies).
What if you grouped small 0.01 payments into mimo transaction, and put it in fee free to a btcguild block?
I refuse to tamper with transaction selection settings in bitcoind. I only use the bitcoind arguments available (minsize, maxsize, prioritysize, mintxfee). I also do not plan on *encouraging* tiny payouts, which is why the fee will be 0.0005, even though they will still be in a sendtomany along with other larger transactions. It's creating a cost-benefit to adding extra clutter to the blockchain. You can get your tiny payouts if you really want them, but not for free.
