There doesn't seem to be an API Call that can do this. At least, I can't find one. Yet, the bitcoin client is able to do it. Any idea how I can do it?

The selected coins are randomized with each send, so an estimate wouldn't be entirely reliable. Someone recently published a patch that added "prepared" transactions, though.

Generally, if you're sending more than a few BTC and the amount you're sending is much less than the total amount of BTC in your wallet, there will be no required fee.

What theymos said.  There's another thread about this, too, and I'll ask here what I asked there:  what is the use case for an 'estimate transaction fee' function? What if the estimate is wrong, what would your application do?

How often do you get the chance to work on a potentially world-changing project?

See the 3rd commit here: https://github.com/bitcoin/bitcoin/pull/289

It introduces RPC calls to prepare a transaction, inspect it, and then choose to send or cancel it.

The estimate being wrong would not be a big problem if there were a way to resend an existing transaction with a fee (or a bigger fee) attached. For the gui I would think the right place for such a command would either be right clicking the 0 confirmation transaction or in the window brought up by double clicking the transaction.

Wouldn't it be possible to send X and the client automatically calculates the fees(Y) for it?
Resulting in X(new) = X(old)-Y?
