Sorry, but you can't. Transactions less than BTC0.01 always require a fee of at least BTC0.0005, to discourage spam. If you use a modified client to send it without an appropriate transaction fee, the transaction will never be confirmed (so don't do that).
What? This isn't accurate. The protocol will happily support sending transactions without fees, it just may take forever to confirm. I sent once just yesterday, took eight hours to confirm.
It is generally better to include transaction fees if you want timely confirmations, but there is nothing preventing sending without one and you will eventually be picked up.
