Open can mean many things. For example all transactions on ripple are publicly available. I'd call that open. You probably want a full open source stack including server software. This is announced, but wasting time of jk here on the forum won't help getting this published faster.

Ripple is already more open than any bank or bitcoin exchange I know of while still (depending on your gateway) being as safe. That alone is a great feature. I agree that an open source server would be great, I am willing to wait though and I trust JoelKatz more in that regard than you.
