I sent a few transactions out recently through bitcoind, and every single one has produced a 0.01 fee, even when the average size of the transactions is 250 bytes (they almost always only had 1 input).

How can I disable the transaction fee when sending smaller amounts?  I'm not that concerned about speed, and I don't like the idea of having a payout of 0.25-0.3 BTC being sent with a 4-5% fee attached.
