But a transaction with a 0.005 BTC output triggers this rule: @p{brk}

Code:
// To limit dust spam, require MIN_TX_FEE/MIN_RELAY_TX_FEE if any output is less than 0.01
 @p{brk}
... so you're back to paying 10kilobytes * 0.0005 BTC / kilobyte == 0.005 BTC to spend those 0.005 BTC. @p{par}

Yes, if you have a large-value, well-aged input then you can combine it with tiny transactions, have a single output greater than 0.01 BTC, and probably get into a block for free. @p{par}

If you want to prototype a smarter coin-selection algorithm, you might start with the 'spendfrom.py' code I wrote as an example of using the raw transactions API: @p{brk}
