Thanks for your answer. I am aware of these zero-fee cases, however I would like to know what is the miimum amount that can be sent for txs with a fee where that fee would be very close or equal to the amount sent.

Why not to try sending amount=1 satoshi with fee=1000 or 10000?

The amount sent and the suggested tx fee must meet at a given combination, I'm looking for that exact point.

<p>What is the absolute minimum amount which when transferred over a tx its value equals the tx's suggested fee? Is it the dust amount of 0.00005430 BTC? How is this value affected when that amount is the only unspent output spent in the tx and when there are more unspent outputs than just this one?</p>

I'm also looking for an answer to this question. When i try to broadcast a small transaction an error stating 'dust' is reported. What is the decimal number encoded into the client that triggers this? What is the magic number?
